ABSTRACT
India is witnessing a rapid growth in construction industry which requires use of
natural resources. Sand is a
in many parts of the country due to restrictions on sand quarrying as it is a non
renewable resource and non
increase in cost of sand signi
need to search for an alternate material. One alternative is the utilization of industrial
by products and waste materials in mortar and concrete, which leads to a sustainable
development. In present study, granulated blast furnace slag (GBFS) is used as an
alternate to river sand. In this investigation, mortar with proportions of 1:3 and 1:4
were considered for 0, 25, 50, 75 and 100 % replacement of natural sand with GBFS
for w/c ratios of 0.45 and 0
prisms of size (230 x 230 x 250) mm. Compressive strength of mortar and masonry
were tested for various replacements. The results confirm that addition of GBFS up to
50% for 1:3 and 25% for 1:4 showed
natural sand. From this study it can be concluded that GBFS can be used as an
alternative to natural sand in mortar applications upto certain replacement. However
further increase in slag caused reduction in c
absorption in GBFS than natural sand.

India is witnessing a rapid growth in construction industry which requires use of
natural resources. Sand is an important constituent of mortar and is becoming scarce
in many parts of the country due to restrictions on sand quarrying as it is a non
renewable resource and non-availability of sand in some parts of the country led to an
increase in cost of sand significantly. As demand is increasing day by day, there is a
need to search for an alternate material. One alternative is the utilization of industrial
by products and waste materials in mortar and concrete, which leads to a sustainable
study, granulated blast furnace slag (GBFS) is used as an
alternate to river sand. In this investigation, mortar with proportions of 1:3 and 1:4
were considered for 0, 25, 50, 75 and 100 % replacement of natural sand with GBFS
for w/c ratios of 0.45 and 0.56. The specimens casted were mortar cubes and masonry
prisms of size (230 x 230 x 250) mm. Compressive strength of mortar and masonry
were tested for various replacements. The results confirm that addition of GBFS up to
50% for 1:3 and 25% for 1:4 showed relatively higher strength when compared with
natural sand. From this study it can be concluded that GBFS can be used as an
alternative to natural sand in mortar applications upto certain replacement. However
further increase in slag caused reduction in compressive strength due to higher water
absorption in GBFS than natural sand.

1. INTRODUCTION
Fine aggregate is one of the important constituents of mortar and concrete and plays a
significant influence on the properties of mortar and concrete. Fine aggregates occupy thrice
the volume of cement which affects the performance of mortar. In general, as demand of
natural sand is quite high in developing countries like India consumption of river sand is
increasing day by day due to mass production of concrete and mortar in construction
activities. The excessive quarrying of sand from river beds resulting in vast depletion of
natural resources, causing a serious threat to future generations and in some parts of the
country there is an increase in the cost of sand due to growing restrictions on quarrying and
non-availability of sand lead to scarcity of sand. In this situation, construction industry and
researchers are looking for a cheap and alternative materials to natural sand. Latest
innovations in concrete technology are focusing on sustainable development by using
industrial by-products possessing similar properties of fine aggregate. The various alternative
materials available for replacement of river sand are manufactured sand, gold mine tailing,
stone powder, quarry saw dust, foundry sand, demolished waste, municipal incineration waste
ash, bottom ash and granulated blast furnace slag (GBFS) [1]. Generally, the use of granulated
blast-furnace slag as a fine aggregate in cement mortar and concrete provides environmental
and economic benefits. GBFS is a by-product obtained from quenching molten iron slag from
the blast furnace in water or steam to produce a glassy, granular product. GBFS is glassy
particle and is granular in nature having similar particle size range like sand. GBFS is
available in huge quantity as an industrial by product in Visakhapatnam at very low cost and
63,000 tonnes of steel slag is produced every year [2]. The particle size distribution of the
GBFS in present work was found to be within the permissible limits of Indian standards.
Present study explores the possibility of using GBFS as replacement of natural sand in mortar
and its applications. In this work, cement mortar mixes 1:3 & 1:4 were selected for 0, 25, 50,
75 and 100% replacements of natural sand with GBFS for w/c ratios of 0.45 and 0.56
respectively.
2. LITERATURE REVIEW
Mohammed Nadeem[2] et al.,investigated the influence of granular slag as fine aggregate in
mortar. In their investigation, cement mortar mixes 1:3, 1:4, 1:5 and 1:6 by volume were
considered for 0, 25, 50, 75 and 100% replacements of natural sand with granular slag with
w/c ratios 0.6, 0.65, 0.70 and 0.72 and tested for compressive strength. The test results
indicate that at 75% replacement level there is an increase in compressive strength for 1:3 and
1:4 mixes and at 50% replacement level for 1:5 and 1:6 mixes. They recommended GBFS
could be utilized as an alternative to natural sand at all replacements for masonry & plastering
applications.
Khalifa. Al-Jabri[3] et al., investigated the effect of copper slag as fine aggregate on the
properties of cement mortars and concrete. In their study various mortar and concrete
mixtures were considered with different proportions of copper slag ranging from 0% (for the
control mixture) to 100% as fine aggregate. Cement mortar mixtures were evaluated for

compressive strength, whereas concrete mixtures were evaluated for workability, density,
compressive strength, tensile strength, flexural strength and durability. The test results
revealed that, the compressive strength of both cement mortar and concrete increased up to
50% and 40% replacements of copper slag. Further increase in copper slag content resulted in
decrease in strength. From their study, they recommended an optimum replacement of 40-
50% of copper slag with fine aggregate in cement mortar and concrete.
Omer Ozkhan[4] et al., investigated on compressive strength and durability of concrete
incorporating coal bottom ash(CBA) and granulated blast furnace slag (GBFS). In their
research, two concrete mixtures M1and M2 were considered. In M1, fine aggregate is
replaced with GBFS and coarse aggregate with CBA for 0, 5, 10, 15, 20, 25, 30%
replacements levels using w/c ratio 0.5 at 7, 28 and 90 days. The test results indicated that
workability of fresh concrete decreased with increase in replacement of fine and coarse
aggregates using GBFS and CBA respectively. For both the mixes, decrease in workability is
due to irregular shape of GBFS and absorption of more water. Based on their findings, they
suggested that the replacement level should be limited to 20% in fine aggregate and coarse
aggregate.
B.V. Venkatarama Reddy [5] et al., investigated the influence of sand grading on the
characteristics of mortar and soil-cement block masonry. Cement mortar (1:6) and cement
lime mortar (1:1:6) with different w/c ratios were considered. They conducted compressive
strength tests on cement mortar. They observed an increase in w/c ratio as fineness of sand
increased. The test results revealed that the compressive strength of cement-lime mortar was
more sensitive to fineness of sand as compared to cement mortar. They concluded that the
masonry prisms made with cement–lime mortar showed a decrease in compressive strength
with finer sand as compared to coarser sand.
M C Nataraja[6] et al., investigated the use of granulated blast furnace slag as fine
aggregate in cement mortar. In their study, cement mortar mixes 1:3 by volume for 0, 25, 50,
75 and 100% replacements of natural sand with granular slag with w/c ratio of 0.50 is
considered. Further they have extended their work to 100% replacement of fine aggregate
with GBFS for w/c ratio of 0.40 and 0.60. They studied the flow characteristics of various
mixes and compressive strength at various ages. Based upon their experimental results, GBFS
could be utilized partially as construction materials for natural sand to mortar appliances.

of brick masonry prisms containing various replacements of GBFS
for 1:3 and 1:4 mortar mixtures is shown in Fig. 9. The crushing strength decreased as the
percentage replacement of sand with GBFS increased. The percentage reduction in crushing
strength is 1.17, 6.12, 25.36 and 30.32 for 25, 50, 75 and 100% replacements respectively.
Similarly, the crushing strength of brick masonry prisms for 1:4 mix proportion decreased by
27.55, 37.99, 54.28 and 65.55 for 25, 50, 75 and 100% replacements respectively. The brick

From the experimental investigation, the fol
• GBFS can be used as an alternative to natural sand and helps in maintaining the environment
as well as economical balance and it is recommended as an alternative to na
producing cement mortar up to 50% replacement.
• The optimum replacement of GBFS for compressive strength of mortar has been found to be
50% for 1:3 mixtures and 25% for 1:4 mixtures.
• Due to higher water absorption of GBFS than natural sand, t
decreased as replacement increased beyond 50% and 25% for 1:3 and 1:4 mortar mixes.
• The optimum replacement of GBFS for crushing strength of masonry prisms are in same line
with mortar strengths and dependent on each other.

From the experimental investigation, the following conclusions were arrived
GBFS can be used as an alternative to natural sand and helps in maintaining the environment
as well as economical balance and it is recommended as an alternative to na
producing cement mortar up to 50% replacement.
The optimum replacement of GBFS for compressive strength of mortar has been found to be
50% for 1:3 mixtures and 25% for 1:4 mixtures.
Due to higher water absorption of GBFS than natural sand, the compressive strength
decreased as replacement increased beyond 50% and 25% for 1:3 and 1:4 mortar mixes.
The optimum replacement of GBFS for crushing strength of masonry prisms are in same line
