Abstract The manufacture of bricks at a reasonable price becomes very difficult due to diminution of the naturally available resources. Excavation of soil for the production of bricks may affect adversely the ecological balance of the nature. Moreover, extraction of river sand is banned by the government and hence there is scarcity of the same for the production of concrete and concrete blocks. All these have obliged the researchers to find a greener alternative for building blocks, which causes minimum destruction of the environment and resources. Foamed concrete can be adopted as a novel and a multipurpose construction material for the production of concrete blocks. An endeavor has been made in this study with the purpose of assessing the feasibility of using quarry fines, an industrial squander, as a swap for fine aggregate in making foamed concrete. Also, river sand, which is scarcely available, is being replaced with manufactured sand in this study. By the use of quarry fines, enormous amount of industrial waste materials can be successfully explored, thereby minimizing environmental pollution as well as the cost of production, subsequently the construction. The study revealed that replacement of manufactured sand by quarry fines in foamed concrete improved its compressive strength and diminished thermal conductivity.

Introduction People have exploited natural resources to produce building materials throughout the ages, and almost all constituents of concrete are derived from natural resources. Due to this year-round exploitation, the environment is threatened from increased pollution from the construction sector. Thus, the construction industry is faced with two problems viz. providing shelter as well as ensuring sustainable development that does not harm the environment. The river sand, the most commonly used fine aggregate for construction purposes and its depletion has led to the use of manufactured sand. Manufactured sand is produced by the crushing of hard rocks and during this process, about 25% of the stone is converted into fine dust called quarry fines or quarry dust (QD). Most of * Sajan K.

the quarry dust is formed while devastating, crushing and screening of extracted rock to make fine aggregate and other products. Thus, quarry dust or quarry fines refer to undersized material or a residue/tailing material subsequent to the mining and dispensation of rocks to develop tiny aggregates, w
