Study of the Mechanical Properties of the Fly Ash Composite Bricks

Abstract

Fly ash brick is an eco-friendly construction material comprised of fly ash, bottom ash, cement and rice husk. Fly ash, a by-product of coal-fired power plants is utilized in place of typical clay or lime in the manufacturing process. One of the key benefits of fly ash brick is its long-term viability. Utilizing fly ash in the manufacturing process lowers waste generated by power stations and the requirement for virgin resources. Fly ash brick also has a reduced carbon impact than typical clay bricks. In terms of performance, fly ash brick offers various benefits. The bricks are more robust and resistant to weathering because they have a higher compressive strength and lower water absorption rate than ordinary clay bricks. They are also well insulated and have a low thermal conductivity. Fly ash brick is also cost-effective since it takes less energy to produce and is less expensive than typical clay bricks. Fly ash bricks are better for the environment since they have a reduced carbon footprint than ordinary clay bricks. They also offer numerous advantages, such as sturdy, long-lasting, and weather-resistant. They also have strong insulation characteristics, which means they can keep a structure cool in the summer and warm in the winter. Fly ash bricks are also a suitable alternative for construction since they are less expensive than regular clay bricks. They also take less energy to manufacture, making them more cost-effective. In this paper, we study the comparison of conventional break and fly ash brick on various dimensions like compressive strength and water absorption test. In this study, the Taguchi technique of parameter design is used to describe the findings of an experimental investigation into the mix proportions of fly ash bricks. With four factors and three levels per factor, the experiments were created using a L9 orthogonal array.
