Abstract—Environmental concerns due to the over-exploitation of sand have led to
restrictions onextraction of sand across India. Thus, the construction industry has huge
demand for a suitable environmentally friendly alternative to sand. On the other hand,
recycling of waste plastic is rarely done in India, with nearly 40% left in landfill. The
dumping of these plastic materials, which degrade at extremely low rates, will lead to high
negative impacts in the society. These plastic wastes will persist in the environment for
very longer period, which is a long-term environmental concern. In order to solve both
these problems, processing the waste and using it as a partial replacement of sand can be
done. As there is strength degradation observed in various previous studies of plastic
incorporation in concrete, Rise Husk Ash (RHA) and Silica Fume (SF) are replaced for
cement to enhance the strength. Keeping the RHA and SF proportion to be constant, the
maximum amount of plastic waste that can be replaced for sand is found out. This paper
mainly focuses on the mechanical behavior of the plastic impregnated concrete. The result
concludes that the maximum amount of plastic that can be partially replaced for sand in
concrete is 30%. Beyond that, the concrete will not satisfy the minimum requirements of
the codal provisions.
Keywords—Silica Fume, Rice Husk Ash, LDPE, Plastic Waste, Impregnated

Abstract - Now a day’s construction field facing many problems, one of them is scarcity
of water. Proper curing is not practically possible in most of the cases. So, the concept self
curing distributes the extra curing water (uniformly) throughout the entire 3-D concrete
microstructure. Self curing agent is more readily available to maintain the saturation of the
cement paste during hydration and reducing the autogenous shrinkage. The aim of the
project is to investigate the strength characteristics i.e compressive strength, split tensile
strength and flexural strength of self curing concrete with silica fume using sodium
polyacrylate and to eliminate the shrinkage effect. The grade of the concrete selected was
M30. Self curing agent used is sodium polyacrylate (0.2, 0.3% and 0.4%) relative to
cement mass. Partial replacement of cement with silica fumes 10% to increase the
pozzolanic properties of the concrete. The optimum mix ratio is taken for the casting of
beam and the flexural strength characteristics was studied and compared with the control
mix.
Key words: Self curing, Sodium polyacrylate, Silica fume, flexural strength.

Abstract— In larger constructions, such as in construction of bridges and buildings, steel-
concrete composite structures are employed to provide high strength and stiffness. These
composite structures function based on the commonly- known fact that concrete is weak in
tension but strong in compression. A natural consequence of this composite action is the
shear flow between the concrete and the steel. In order to prevent slip from occurring
between the concrete and steel sections, shear connectors are provided, thereby allowing
the two components to behave as one1. The focus of this study is on shear connectors of
the flexible type, which resist shear forces by bending, tension or shearing at the point of
connection between the connector and the steel beam. The steel concrete composite
construction has become an effective construction practice in the recent years. The cold
form profiled sheet acts a platform for during the construction phase and acts as an external
reinforcement after the construction. In steel concrete composite construction, the shear
connectors transfer the longitudinal shear force across the steel flange/concrete interface.
The ability to transfer the longitudinal shear force by shear connectors mainly depends on
the strength of concrete against longitudinal cracking and mechanical properties of the
shear connectors. Head stud and L-shaped shear connectors will be used and tested in this
project.
Keywords— Composite slab, Shear connectors, Cold form steel sheet, Head stud
connector, L-shaped connector.

Abstract—This paper presents comparison of bonding strength and compressive strength
between steel and concrete. The bond strength measures the effectiveness of the grip
between concrete and steel.In pullout tests on Mild steel bars , the maximum load
generally represents the bond strength that can be developed between concrete and
steel.With Mild steel bars the maximum load is not very different from the load at the
visible slip,But in the case of deformed bar,the maximum load may corresponds to a large
slip which may not be obtained in practice before other type of failure occur.It is preferable
therefore than comparing plain and deformed bar determined not only the maximum
load,But also the load arbitrary amount of slip and also plot the complete load slip curves
for the plain and deformed bar under comparison.In bonding strength test,comparison of
the load at a relative movement(slip) between steel and concrete of 0.125mm at the free
end of the bar in a pullout test. The analysis of the test data shows that a significant co-
relation exists between the compressive strength of cube cured under standard conditions
and the bonding strength of concrete.
Keywords—Mild steel bar, pullout test, bonding strength

Abstract-Cold formed steel members are extensively used in the building construction
industry, especially in residential, commercial and industrial buildings. In recent times, the
use of cold formed high strength steel members has rapidly increased. Cold formed steel
(CFS) cross sections can be optimized to increase their load carrying capacity, leading to
more efficient and economical structural systems. Buildings framed from cold formed steel
members are becoming increasingly common. Significant research has been conducted on
individual cold formed steel members, due to the open nature of the sections, torsion
induces warping in the beam. This paper summarizes the research on the behavior of cold-
formed steel beams subject to torsion. The attention is focused on beams subject to torque,
because of the transverse loads.

Abstract-Geopolymers are materials based on pure alumino-silicate source materials such
as fly ash; granulated blast furnace slag obtained from industrial, activated with either with
the combination of sodium silicate and sodium hydroxide or with the combination of
potassium hydroxide and potassium silicate. High alkaline solutions are used to induce the
silicon and aluminum atoms in the source material to dissolve and form Geopolymer gel.
The sol gel formation (or polymerization) may be assisted by application of heat, followed
by drying. The usage of ground granulated blast furnace slug made the geopolymer motor
to cure at the room temperature. The Geopolymer gel binds the loose coarse aggregate, fine
aggregate and unreacted source material to form Geopolymer composites. The Portland
cement free Geopolymer composites have many advantages like less curing time, earlier
development of higher mechanical strength, very little drying shrinkage and very low
creep, excellent resistance to sulfate attack, good acid resistance and resistance to high
temperature. The strength development in Geopolymer composites depends on the
chemical composition, morphology and reactivity of source materials, chemical
composition of activating solution and curing process. The Geopolymer with the
combination of mesh increase the compressive strength of the concrete.

resource management planners. In recent times, with the rapid development in the field of
Remote Sensing and Geographic Information System (RS and GIS) provides lots of new
opportunities and applications for researchers and planners. LULC change dynamics are
effectively derived from Remote sensing based data sets. This work focused on the study
of LULC changes and urban expansion patterns for the Tiruchirappalli District and its
environs. Supervised classification of Landsat images for the years 1996 and 2016 was
carried out to understand the development as well as degradation in the form of conversion
from one class to other. Significant expansion in builtup class and decrease in cropland and
vegetation classes was observed. This study serves planners, researchers and decision
makers to plan for solving environmental management issues related to urban expansion
and LULC change dynamics.

Abstract -Conventional brick is the most basic building material for the major
construction of structures. Due to rapid growth and development in the construction field,
Civil Engineers are in search for a new building material and techniques on the basis of
economy, durability and efficiency which serves as an alternative for the conventional
brick. The change in the masonry system is due to the factors like reduction in man power
and speed of construction. This investigation compares the conventional brick and fly ash
based interlockingblock on the basis of structural aspects such as Compressive strength,
Impact resistance, Energy absorption and Bond strength. Interlocking block gives the
better results on strength and durability when compared with conventional brick. The
compressive strength of the interlocking block increases by 15% to 20% when compared
with conventional brick. The bond strength of interlocking block is greater than the
conventional brick. The interlocking block can withstand temperature more than that of
nominal brick. The interlocking block has been utilized in both load bearing and non –
load bearing masonry system.

Abstract -Plastic and electronic wastes are the most commonly discarded synthetic wastes
that contribute to environmental pollution. One solution to environmental pollution
includes recycling these plastic wastes as synthetic fibre and incorporating them into
concrete. This research aims to investigate and evaluate the performance of concrete using
waste plastics. Waste plastic bottles, coffee straw and outer casing insulation of electrical
wire are used in this project and fly ash is being used as a partial replacement for cement.
The waste plastics are taken in a ratio of 1%, 1.5% and 2% respectively to the weight of
cement. Their properties are tested to study the characteristic strength, split tensile and
flexural strength and to find optimal utilization of these waste plastics without modifying
its nature. Results indicate that an increase in fiber volume improves tensile strength of
concrete. Incorporation of high-volume fiber with concrete results in a substantial amount
of fibres bridging and crossing the fractured sections, thereby activating failure resistance
mechanisms

Abstract-The global use of concrete is second only to water. As the demand for concrete
as a construction material increases, so also the demand for Portland cement. The global
warming is caused by the emission of greenhouse gases, such as carbon dioxide (CO2), to
the atmosphere by human activities. Among the greenhouse gases, CO2 contributes about
65% of global warming. In terms of global warming, the geopolymer technology could
significantly reduce the CO2 emission to the atmosphere caused by the cement industries.
The Geopolymer gel binds the loose coarse aggregate, fine aggregate and unreacted source
material to form Geopolymer composites. The Portland cement free Geopolymer
composites have many advantages like less curing time, earlier development of higher
mechanical strength, very little drying shrinkage and very low creep, excellent resistance to
sulphate attack, good acid resistance and resistance to high temperature. The concrete
cubes are made by varying the fly-ash content by 500 kg/m3,450 kg/m3, 400 kg/m3. The
Geopolymer with the combination of mesh in different layers such as 1 layer, 2 layer and 3
layers increases the compressive strength of the concrete as well as mortar and the
combination of 3 layers in concrete provides maximum results in compression strength.

Abstract—Numerous natural issues are related with thecreation of Ordinary Portland
cement. Vast measure of thecarbon dioxide discharges amid the assembling of
OrdinaryPortland cement because of the calcinations on limestone andignition on non-
renewable energy source is in the request ofone ton for each ton of OPC created. The
degree of vitalityrequired to create Ordinary Portland cement is just by steel.On the second
face the copious accessibility of fly ash overallmakes chance to utilize this side-effect of
consuming coal, as asubstitute for Ordinary Portland bond to fabricate concrete.Hence, one
of the approaches to create ecological invitingconcrete called Geopolymer, is to lessen the
utilization ofOrdinary Portland Cement by utilizing different types ofbinders to make
concrete. In geo-polymer concrete, the GGBSand silicon and the aluminium in the low-
calcium (Class F) flyash respond with a alkaline activator that is a mix of sodiumsilicate
and sodium hydroxide solutions for structure theGeopolymer that binds the aggregates and
other unreactedmaterials. Geopolymer concrete carries on like conventionalconcrete yet
have slight increment in strength and significantincrement in twisting properties.
Geopolymer concrete is 25percent monetarily valuable than standard concrete. Fly
ashsubstance of 500 Kg/m3, 450 Kg/m3 and 400 Kg/m3 are trailedin Geopolymer
concrete. From which the fly ash content of 400Kg/m3 gives the more strength and
workability whencontrasted with conventional concrete.

Abstract-The open holed plates are widely used in bolted connections and are made of
aluminum, steel, cold formed steel structures and FRP composites. The presence of these
perforated holes in structural members may complicate the design process. Thus, the
industry needs simplified local buckling prediction methods for predicting the elastic
critical stress and load deformation response. The perforated plates when subjected to
compression experience buckling and instability. The presence of slots may create unique
buckling modes and can either increase or decrease the plate’s critical elastic buckling
stress based on the geometry, shape and pattern of the holes and their spacing. This
research would explore the possible buckling failure modes, elastic stiffness, elastic critical
stress, elastic buckling behaviour, Stress intensity factor and load deformation response of
cold formed stainless steel plates and FRP composites for varied load conditions, shape,
size, geometry, aspect ratio and pattern of perforated plates using Eigen value buckling
analysis by finite element modelling.Thebehaviour of plates would be analysed for four
loading cases including concentrated edge loading, asymmetric partial loading at opposite
edges, partial loading at the centre of opposite edges and partial loading at the two ends of
the opposite edges.

Abstract -Ferrocement is a type of thin wall reinforced concrete reinforced with closely
spaced layersof continuous and relatively small size wire mesh. The mesh may be made of
metallic orother suitable materials. Mortar provides the mass and wire mesh imparts tensile
strength andductility. This paper presents an experimental and analytical investigation to
compare theflexural behaviour of partially replaced metakaolin and fly ash with control
ferrocements.Inclusion of metakaolin in ferrocement matrix influences properties of the
mortar. Fly ash isone of the residues from thermal powerplant which makes mortar more
durable. Themetakaolin-fly ash mortars with 15% metakaolin and 5-25% of fly ash
replacement in theincrements of 5% with cement were made. Constant water to
cementitious ratio of 0.5maintained for all mortars. The control ferrocement has no
replacement of fly ash andmetakaolin. Galvanized hexagonal steel wire meshes were used
as mesh reinforcement.Ferrocement panel size of 470 mm x 940 mm,40 mm thickness has
been adopted.First phase of work carries analytical work done by ANSYS® Workbench
18.2. In this phase,the work has been carried out to show the variation between
conventional panel andferrocement panel. Further in second phase, the flexural strength of
the ferrocement panel hasbeen studied by casting mortar cubes followed by panel casting

Abstract-In precast structures, achieving the monolithic behavior of the joint is the
majorproblem faced by the engineers. One of the effective and possible solutions is
creating anovel joint. In order to model a novel joint, various failure modes are studied and
the joint isdesigned in such a way that it can sustain all the failures in an enhanced manner.
Themodeling of the precast joint in the ABAQUS involves simulation of long bolts, base
plates,surface stiffener plates and hyper-elastic materials and assembling them. Contact
models areprovided in order to ensure the contact between the regions and interaction data
are fed todefine the degree of contact between the materials. The response of the novel
precast beam-column joint as well as the conventional beam-column joint is analyzed
under cyclic loadingand the results are compared. The results depict that energy dissipation
capacity, stiffnessdegradation and ductility ratio of both the precast joint and conventional
joint are nearlysimilar. Thus, the designed precast joint was found to be a significant
solution for achievingthe monolithic behaviour, which makes it to have better applicability
in the seismic regions.

Abstract- Concrete is the most important construction material. Among all these
ingredients,fine aggregate plays the major role in concrete. In present era, the availability
of natural sandis very less. To overcome this problem we could use alternative material,
i.e. waste materialslike crumb rubber. The disposal of waste crumb rubber has shown an
adverse impact on theecological balance causing pollution all over the world. In such a
case, an alternative solutionfor the use of rubber and their products is to incorporate it into
concrete, as a partialreplacement to natural fine aggregate. The use of crumb rubber in
construction is increasing.Concrete mixed with crumb rubber has better toughness than the
ordinary concrete, and alsohas a better heat insulation and sound insulation properties and
better energy absorption.Rubber mixed with concrete increases the workability but
decreases the mechanicalproperties including compressive strength, split tensile strength
and flexural strength. In orderto overcome this problem we have to use treated rubber,
GGBS, and silica fume. The silicafume and GGBS when mixed with concrete increasing
the strength.
Key words: waste material, crumb rubber, silica fume, GGBS, treated rubber,

Abstract-Self-compacting concrete (SCC) is a stable and cohesive high consistency
concrete mix with enhanced filling ability properties that reduce the need for mechanical
compaction. Day by day due to scarcity of raw materials for concrete there is a need to find
the alternate solution for conserving raw materials by using alternate materials. The use of
quartz sand as replacement for sand is an economical solution for making the concrete.
This paper aims to focus corrosion study of self-compacting concrete made with industrial
wastes, i.e., marble sludge powder(MSP) and quartz sand(QS).MSP can be used as a filler
and it helps to reduce total voids content in concrete and the usage of quartz sand is
proposed as partial replacement of fine aggregate in production of SCC. The main purpose
of this paper establishes the optimum percentage of replacement of quartz sand and marble
powder in order to obtain high strength.

Abstract−
Now a day’s construction field facing many problems one of them is
scarcity of water. Proper curing is not practically possible in most of the cases. So, the
concept self curing distributes the extra curing water (uniformly) throughout the entire 3-D
concrete microstructure so that it is more readily available to maintain the saturation of the
cement paste during hydration and reducing the autogenous shrinkage. The objective of
the project is to investigate the strength characteristics of self curing concrete with silica
fume incorporating different chemical curing agent and to eliminate the shrinkage effect.
The grade of concrete selected was M25.The self curing agents used is polyethylene
glycol-6000 (0.5%, 1% and 1.5%) relative to cement mass. The optimum mix ratio is taken
for the casting of beam and the strength characteristics will be studied and compared with
the control mix. The effect of variation in strength parameters, elastic properties and
shrinkage i.e., Compressive Strength were studied for different dosage of self curing agent
and shrinkage reducing agent PEG in order to reduce early-age shrinkage and at the same
time, maintains the mechanical properties and durability of concrete.
