1.INTRODUCTION:

The municipality solid waste incineration

bottom ash contains non ferrous and ferrous matter,

burned and unburned materials such as

bricks,glass,E waste,stone,paper,plastic etc.the ash

content reduces the volume and mass of the solid

waste and also land filling also decreased.130

Micron particle size MSWI ash is chosen for this

experiment. Properties has been evaluated by These

properties were then compared to conventional

concrete mixtures made with natural silica sand to

enlarge the beneficial make use of crushed

limestone concrete and emphasize its prospective

In India, almost all the Civil Engineering

constructions are carried out using crushed lime s.

Due to weighty amplify in the construction

behavior, the crushed lime stone which are the

conformist fine aggregate is under exhaustion and

also, at the present time an heightened deficiency

of these materials is practiced..

II. MATERIALS AND THIER PHYSICAL

PROPERTIES:

Fig 2.1 shows the required materials

A. Cement Ordinary Portland cement of 43 grade

manufactured by RAMCO CEMENT was used for

the experiment. Portland cement is most common

type of cement in general used around the world

because it is a basic ingredient of mortar, stucco

and most non specially grout. It is manufactured in

the form of different grades; the most common in

India are Grade 53, Grade 43. OPC is

manufactured by burning siliceous materials like

limestone at 1400.C and thereafter grinding it with

gypsum. The OPC grade 43 (used in this project) is

known for its rich quality and high durability

The Cement used was ordinary Portland Cement

(PPC) manufactured by Ultratech, conforming to

IS: 1489(PT1):1991[21]. The various properties of

cement were in accord with IS: 4031-1991[14] and

the results are tabulated in tabulated 2.1

Ferraris et al proposed melting MSWI ash at

1450.C and grinding the resulting slag to particles

smaller than 90mm which can be used and filler or

supplementary cementations material. Similar

approach studied Lee and Rao. This material was

used for production of blended cement. Remand et

al studied effect of untreated MSWI ash on

technological properties of cement mortars. The fly

ash caused significant increase of setting time and

decrease of workability and strength

III METHODOLOGY

A. Introduction

The in attendance investigation and the

proportional studies on the strength distinctiveness

of the crushed lime stone as fine aggregate and

MSWI ash as cement in concrete with conservative

concrete was passed out. The typical tests of all

resources have been carried out in the laboratory as

per the appropriate codes

B.TESTING MACHINE: the testing machine of capacity 40000kgF is used.

The apparatus has been so planned to congregate

the uncomplicated and unswerving unit having bare

minimum heaviness and measurement for the

above load capacity, devoid of seated steel platen at

the top and a changeable steel platen at the bottom.

This apparatus can also used for split tensile

strength test. The beam specimens are experienced

using hydraulically operated flexural testing. the

code for dissimilar specimens. The bed of the

testing mechanism is provided with two Load can

be functional at the required rate individual in. This

roller can be preset to the bed such that the

remoteness from center to center can be adjusted

for 400mm as well as 600mm.The load can be

applied

through one comparable roller mounted at the

midpoint of the rollers.

cast iron mould meeting the requirements to

IS:516 -1959were worn to cast cube sample of

dimension 150mmX150mmX150mm.

IV. MIX DESIGN

In this analysis M30 grade of concrete was well

thought-out and intended using a course of action

by IS: 10262-2009[18]. Subsequent to making an

allowance for many experiment mixes, the mix

proportions for control concrete were as 1:1.9:2.8

with water cement ratio of 0.5. The computation of

quantities of constituent necessitate for dissimilar

concrete mixes are given in Appendix-I. The Batch

recognition and their individual bulk composition

is as shown in table 4.1

V. TESTS ON FRESH CONCRETE AND

HARDENED CONCRETE

A. Fresh Concrete Concrete mixes equipped were hardened for

its fresh properties like workability such as slump

test and compaction factor test.

B. Slump test Slump test is a most frequently used scheme

of calculating the consistency of the concrete which

can be engaged whichever in laboratory or at

location of work. It is used to suitably as a manage

analysis and provides an suggestion of the

standardization of concrete from consignment to

consignment. Supplementary information on

workability and quality of concrete can be attained

by examining the approach in which concrete

slumps. The bend and deformations give you an

idea about the distinguishing of concrete with high

opinion to propensity for segregation [9].

C. Compacting factor test

The compacting factor test is intended first

and foremost for use in the laboratory but it

preserve as well be used in the field. It is more

accurate and responsive than the slump test and is

predominantly functional for concrete mixes of

very low workability as are as a rule used when

concrete is to be compacted by vibration. Such dry

concrete are not sensitive to slump test.

D. Compression test on concrete The most common of all tests is the

compressive strength test since the desirable

characteristics of concrete are qualitative related to

its strength. The compression test was conducted

on cubes at the age of 7 days, 28 days and 45 days

of curing respectively and confirming to IS 516-

1959[17]. Cubes stored in water were tested

immediately on removal from water in the damp

condition. The surface water and grit was wiped off

from the specimen. The actual dimensions and

weight of the specimen was noted.

The specimen was placed on the testing

platform of the compression testing machine in

such way the load was applied to the surface other

than the top and bottom surface as cast. The load

was applied without shock and increase until the

resistance of the specimen to the increasing load

broke down and no greater load was sustained. The

total load applied at failure was recorded. The

maximum load applied divided by its cross

sectional area given the compressive strength.

Averages of three specimens were taken, provided

the individual variation was not more than ± 15

percent of the average [9].

V. RESULTS AND DISCUSSION

1. General

Comprehensive investigational explorations

were passed out on the consequence of

municipality solid waste incineration and crushed

limestone powder substituting cement and fine

aggregate in concrete. The investigational results

were conversed in the subsequent segments.

2. Density of the samples: The densities of dissimilar samples are

calculated depends on dimension of the sample the

results are tabulated in

3. Compression test on concrete The most common of all tests is the

compressive strength test since the desirable

characteristics of concrete are qualitative related to

its strength. The compression test was conducted

on cubes at the age of 7 days, 28 days and 45 days

4. Cube Compression Strength Results

The compression strength investigation

consequence for a variety of concrete mixes is

tabulated in Table 5.3, after curing period of 7,14,

28, days. The rate ranges from 35 to 31.5 for R0 to

R100 respectively for 28 days. Fig 5.3 clearly

showed that 7, 28 &14 days compressive strength

decreased gradually as percentage of MSWI ash

and lime stone increased.

3. Fresh Properties of Concrete Mixes

High cementcontent, both the

comparatively far above the ground quantity of

water and the enlarge in cement paste supply in

enhancing the workability of the concrete mixture.

Fresh concrete density reduces upon an increase in

either the We/C ratio or the slump. This may be

ascribable to the fact that voids in concrete that are

at the start filled with filler become more and more

filled with water (material lighter than filler) As a

result, for a given We/C ratio, the better-off

concrete mixtures tend to have the lowly fresh

density due to the superior quantity of water in

attendance in them.

4. CONCLUSION

In this study, the MSWI ash and crushed

lime stone powder is used to replace as the

percentage of 10%,15%,20% wt progressively. The

possessions of mortars

in fresh and hardened positions are examined, and

the influential features are considered. The

subsequent termination

can be drawn in fig 6.3.it shows the compressive

strength is increased at 15% replacement. after the

addition the strength has been reduced gradually.

1) The substitution of cement by MSWI ash has

a insignificant manipulate on the flow ability of

mortar, and the particle character and porosity of

bottom ash throw in to it.

2) The flexural and compressive strengths of all

the mortars with MSWIash reduce at all curing

ages, and the reduce of the flexural strength is

inferior than compressive strength. Cement with

MSWI ashes, with 10%and 15% decrease after 28

days curing for compressive strength, respectively

3) Mixture quantity of concrete complicated

with crushed limestone sand can be

sufficiently resolute using average addition

performances complete that the mixing

water is accurately anticipated.

4)It emerges that higher limits on the quantity

of fines content in the crushed sand could

be allowed for provided that the fines are clean and

properly graded.

5) Crushed limestone concrete compulsory

added mixing water than normal silica

sand concrete to reach a particular fresh activities.

A advanced amount of paste is also

wanted for crushed sand concrete to get hold of

average range strength.

6)comparable or improved mechanical strength

than conservative natural sand concrete can be

formed using crushed limestone sand as fine

aggregate with a SP. on the other hand, to

prevail over the unfavorable result of crushed sand

such as consistency and figure, a superior than

normally used dosage of SP is required. The

optimum dosage of SP needs to be

unwavering for each cement and sand content. The

inclusion of SP reduces the water
