Application of recycled soil and sand in brick production over conventional clay Brick: A sustainable alternative

Abstract

Urbanization in India is rapidly growing. To make building materials sustainable now-in days the focus is to increase the application of supplementary materials for manufacturing various building products like tiles, pipes, bricks, etc. The construction and demolition waste production rate is increasing in India day by day. It is approximately estimated that only in the construction sector of India, 10–12 million tons of building and demolition wastes are produced each year. In this research construction and demolition waste is utilized for one of the essential building products for manufacturing of bricks as an alternative to a conventional brick. For the casting of bricks 20 %, 40 %, 60 %, and 80 % of recycled soil and recycled sand are utilized as an alternative to conventional soil along with bagasse ash. After satisfying all the requirements of the material relates specifications, the properties of brick were investigated. Results of compressive strength with 20 % replacement of natural soil by recycled sand and soil are showing maximum results. Results of Compressive strength with recycled sand have 5.87 N/mm2 and for recycled sand having 7.04 N/mm2.For the same strength rate waster absorption was maximum up to 13 % only, which satisfies the requirement of the standard. The efflorescence rate for these bricks is also noticed to be moderate. From this research investigation, we can conclude that with quality control practice if this material has been utilized for the manufacturing of bricks then we can say the natural soil is up to 20 %. we are able to conclude that the application of recycled soil and Sand helps to improve sustainability and reduce the illegal dumping of material.
