Over-Burnt Bricks in Sustainable Construction a Viable Alternative to Natural Aggregates

Brick production plays a vital role in the construction industry, where high temperatures are used to shape and fire clay or shale into durable building materials. However, over-burnt bricks—resulting from excessive or prolonged heating—often become brittle, darkened, and structurally compromised, making them unsuitable for typical construction applications. These over-burnt bricks are commonly discarded as waste, contributing to landfill build up and environmental concerns. In contrast, repurposing over-burnt bricks offers an opportunity for sustainable waste management and resource conservation. When crushed into a material known as brick blast, these over-burnt bricks can serve as a substitute for coarse aggregates in concrete or partially replace coarse aggregate, reducing the dependence on natural resources. An experimental investigation was conducted to assess the potential of using brickblast in concrete production, focusing on its impact on mechanical properties, workability, and durability. Early results indicated that brickblast not only serves as an effective waste disposal method but also enhances concrete strength and durability, offering a more eco-friendly alternative to conventional concrete. By incorporating brickblast, energy consumption and carbon emissions from cement production can be minimized, while contributing to a circular economy. This innovative approach supports sustainability in the construction industry by reducing landfill waste, conserving natural aggregates, and providing a cost-effective solution to enhance concrete performance. Ultimately, utilizing over-burnt bricks in concrete production can lead to more sustainable and environmentally responsible building practices.
