INVESTIGATION IN DEVELOPING LOW-COST CONCRETE BY USING BRICK POWDER AND QUARRY STONE DUST

Abstract

The increased emphasis on the life-cycle cost analysis for building project requires that new attention to be focused on service life and durability of concrete structures. Durability is the ability to resist weathering action, chemical attack or any other process of deterioration. Concrete?s great versatility and relative economy in filling wide range needs has made it a competitive building material. This high demand for concrete in construction lead to the increase in the release of carbon dioxide in cement production and also to the scarcity of natural river sand. So there is an urge to replace the conventional concrete materials. Materials like Brick powder (BP) and Quarry dust (QD) are chosen based on the criteria of cost and durability properties. This project is concerned with the evaluation of changes in compressive strength and flexural strength in different mixes of M40 Grade concrete which include conventional aggregate concrete, concrete with 10% replacement of cement by brick powder(BP) and  fine aggregates with varying percentages of 0%,5%, 10%, 15%, 20% & 25% by Quarry Dust (QD). We can conclude that concretes made by Brick Powder and Quarry Sand Dust have given good strength and durable properties when compared to conventional concrete in severe environment.
