They evaluated various concrete mixes with partial replacement of cement with varying percentage of quarry dust (10%, 15%, 20%, 25%, 30%, 35%, and 40%). From the experimental studies, they reported that 25% partial replacement of cement with quarry dust showed improvement in hardened of concrete.
Journals For Replacement Of Sand By Quarry Dust In Concrete. The present paper deals with partial replacement of cement with quarry dust and metakaolin which are having silica used as admixture for making concreteirst quarry dust is made partial replacement of cement and found that 25 of partial replacement is beneficial to concrete without loss of standard strength of cement.
This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete. Attempts have been made to study the properties of concrete and to investigate some properties of Quarry Dust the suitability of those properties to enable them to be used as partial replacement materials for sand in concrete.
investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.
Yes As quarry dust(also called as crushed sand) is a byproduct obtained after crushing of stones(rocks) to make aggregates. * Results have shown that the concrete ...
Concrete plays the key role and a large quantum of concrete is being utilized in every construction practices. Natural river sand is one of the key ingredients of concrete, is becoming expensive due to excessive cost of transportation from sources.
clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement. Index Terms- Concrete, quarry dust, river sand, compressive strength. I. INTRODUCTION oncrete is the most widely used composite material today.
