RESEARCH ON THE PRODUCTION OF AFFORDABLE CONCRETE VIA THE UTILISATION OF BRICK POWDER AND QUARRY STONE DUST
K Rajanikara Swamy, K Sai Kiran
Abstract
The lifespan and durability of concrete structures need to receive more attention due to the growing emphasis on life-cycle cost analysis for construction projects. The capacity to withstand weathering, chemical erosion, or any other deteriorating process is known as durability. Concrete is a competitive building material because of its exceptional adaptability and relative affordability in meeting a variety of purposes. Due to the increased demand for concrete in building, there is a shortage of naturally occurring river sand and a rise in carbon dioxide emissions from the cement industry. Therefore, there's a push to switch out the traditional concrete materials. Cost and durability features are taken into consideration when selecting materials such as quarry dust (QD) and brick powder (BP). This project examines how different mixes of M40 Grade concrete, such as conventional aggregate concrete, concrete with 10% cement replacement by brick powder (BP), and fine aggregates with different percentages of 0%, 5%, 10%, 15%, 20%, and 25% by quarry dust (QD), affect compressive strength and flexural strength. When compared to traditional concrete, we can conclude that concretes created using brick powder and quarry sand dust have good strength and enduring qualities in harsh environments.
