sand replacement with quarry dust project

The optimum replacement level of SD as fine aggregates was 40% [2].One of the waste materials such as quarry dust used as a good alternative for sand in mixtures which gives more strength at 50% ...
This project is an experimental investigation into the effect of using quarry dust with iron filing as a partial replacement for fine aggregates [sand] in concrete production.
Quarry dust is ideal for these jobs and is expected to be the future and likely replacement for sand in construction project, since river sand is fast becoming scarce and very expensive. Strength When Needed . Sand is obtained from river beds, and is its availability is becoming challenging at reasonable price.
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.
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.
-The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials.
