of granite fines to fine aggregate are 0, 10, 20, 30, 40, 50 and 100 for M20 mix proportions, specimens are tested after 28 days of curing, for compression strength, flexural and split tensile strength. The specimen casted with 40 % replacement of granite fines to fine aggregate gives higher strength when compared to control specimen.
quarry dust can be used as a replacement for fine aggregate. It is found that 50% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases after replacement of fine aggregate. . Key Words: fine aggregate, quarry dust, compressive strength, replacement. 1. INTRODUCTION

facing. In this paper, the issues of environmental and economic concern are addressed by the use of quarry dust as partial replacement of fine aggregates in concrete. Fine aggregates were replaced by quarry dust as 0%, 10%, 20%, 30% and 40% by weight for M-25 mix. The concrete specimens were tested for compressive strength,
quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and ...
This research aims to have an alternative fine aggregate in geo polymer concrete. In this regard, geo polymer concrete is produced with alkaline activated fly ash as geo polymer binder and quarry stone dust is used as fine aggregate instead of natural sand because it is most economical.
