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

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.

2.1. Objective & Scope of Study

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.

Compressive strength of brick masonry prisms of natural sand with GBFS at 28 days

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

with mortar strengths and dependent on each other.
