Impact And Benefit Analysis Of Using Lightweight Concrete Block In Building Construction

Abstract

Traditional constructions use burned clay bricks, which have drawbacks. The construction industry has grown interested in sustainable and creative building materials instead of burnt clay bricks to address environmental issues, improve construction efficiency, and improve building performance. Clay bricks are small but hefty and require a lot of concrete to unite and plaster from both sides to fill the wall surface's unevenness and improve the quality. However, lightweight concrete blocks are a viable alternative to clay bricks or standard concrete blocks due to their reduced weight and enhanced insulation. This thesis examines the advantages of lightweight concrete blocks in building construction. Lightweight blocks lowered mortar use, making them stronger, faster, and more durable than brick masonry. Due to its inexpensive cost, lightweight (about 30% less than clay bricks), and acoustic and thermal insulation, lightweight blocks are 10 times the size of clay bricks and are growing in demand. This study examines how lightweight concrete blocks affect building structures, focusing on spearing's impact on cost and weight. The study compares lightweight concrete blocks to conventional ones in mechanical, thermal, and environmental qualities. The study examines lightweight concrete blocks' structural integrity, thermal insulation, and environmental benefits through literature review and lab testing. Results show that lightweight concrete blocks have comparable mechanical strength to conventional ones, decreasing construction project carbon footprints. This thesis also investigates the economics of lightweight concrete blocks in buildings. A cost-benefit study considers material costs, construction time, energy savings, and long-term maintenance. The findings show that builders and developers can afford lightweight concrete blocks after the initial outlay. This research considers the social impact of lightweight concrete blocks in addition to the technical and economic aspects, promoting sustainable and efficient building practices and a more environmentally friendly and economically viable construction industr
