ABSTRACT Quarry dust a waste from the stone crushing unit accounts 25% of the final product from stone crushing unit. This quarry

dust which is released directly into environment can cause environmental pollution. To reduce the impact of the quarry dust

on environment and human, this waste can be used to produce new products or can be used as admixture in concrete so that

the natural resources are used efficiently and hence environmental waste can be reduced. Here quarry dust is used for partial

replacement of cement in concrete for studying the strength property of concrete. The aim of the experiment is to find the

maximum content of quarry dust partial replacement of cement in concrete. The percentages of quarry dust partial

replacement of cement in concrete are 0, 10%, 15%, 20%, 25%, 30%, 35%, and 40%. M20, M30, M40 grade concrete cubes

of 150x150x150mm size were cast for conducting compressive strength test. From the experimental studies 25% of partial

replacement of cement with quarry dust improved hardened concrete properties.

KEY WORDS: quarry dust, compressive strength, and partial replacement.

INTRODUCTION:

Advancement in utilization of wastes in concrete as

admixture reduces pollutants in environment and

maximizes usage of natural resources. During the

production of cement Co2 is produced which cause

global warming. By reducing cement consumption

environment can be protected. An attempt was made

to partially replace the cement with waste material

quarry dust with an aim not to loose the strength far

from original concrete mix.

From the observations of test results, cement can be

replaced with 25% of quarry dust in concrete. The

physical and mechanical properties of materials used

in concrete were investigated. For each replacement 6

cubes were cast for measuring 7days and 28days

compressive strength.

MATERIALS:

Quarry dust: quarry dust is collected from local

stone crushing units of chowdavaram village, Guntur,

Andhra Pradesh. It was initially dry in condition

when collected and was sieved by IS: 90 micron

sieve before mixing in concrete. Specific gravity

observed for quarry dust is 2.5.

AGGREGATES:

Fine aggregate: Krishna river sand confirmed to

grading zone-III as per IS: 383-1970, having specific

gravity of 2.61 and fineness modulus of 2.9 has been

used as fine aggregate for this study.

Coarse aggregate: coarse aggregate obtained from

local quarry units has been used for this study.

Maximum size of aggregate used is 20mm with

specific gravity of 2.73.

Cement: Portland pozzolana cement conforming to

IS: 269:1976 and IS: 4031-1967 was used in this

study. The cement is of 53Grade and the tests

conducted on cement are tabulated in Table. No.1. Table No. 1 Properties of cement

Water: Potable tap water available in laboratory was

used for mixing and curing of concrete.

Mix design procedure: In present study M20, M30,

M40 grades concrete were designed as per IS: 10262-

2009. The weight ratios of mix proportions are

tabulated in Table. No. 2 Table. No. 2 Mix proportions

Experimental Test Setup: concrete cubes

confirming to IS: 516:1964 of size 150x150x150mm

were cast. Total 144 cubes were cast for

determination of compressive strength. After 24

hours the moulds were de-moulded and subjected to

water curing. Before testing, the cubes were air dried

for 2 hours. Crushing loads were noted and average

compressive strength of 3 specimens is determined at

7 days and 28 days shown in table 3 and 4

respectively of various mix proportions.

RESULTS: Table No. 3: Test results of 7 days compressive strength,

(N/mm2) of M20, M30, M40 Grades concrete with

partial replacement of cement with quarry dust.

Table No.4: Test results of 28 days compressive strength

(N/mm2) of M20, M30, M40 Grade concrete with partial

replacement of cement with quarry dust.

Fig: 2 Show 28 days compressive strength(N/mm2).

CONCLUSIONS:

• Cement can be replaced with quarry dust up

to 25% without much loss in compressive

strength.

• Water to powder ratios of 0.5, 0.4, 0.35 for

M20, M30, M40 respectively were

maintained for all the percentage

replacements for workability.

• From the results a marginal decrease in

compressive strength is observed up to 25%

cement replaced with quarry dust.

• Considerable decrease in compressive

strength was observed from 25% cement

replaced with quarry dust.

• From 20% to 25% cement replaced with

quarry dust 7 days compressive strength is

slightly increased.
