摘要：In recent days construction industry focuses on other than conventional concrete in infrastructural purposes like building etc., due to excess usage of cement, sand and other aggregates which leads depreciation of natural resources and effects on the environment. By utilization of lightweight bricks and foam concrete which reduces not only its self-weight but also improve resistance against heat and sound insulation and architectural features. The density of foam concrete varies from 300 to 1800kg/m3. Foam concrete composes of cement, water, fly ash and foaming agent without coarse aggregate. The function of foam is to create air bubbles in the cement-based slurry. The density of foam concrete depends on the quantity of foam added. The foam creates several pores with this effect; it has low thermal conductivity. As density of foam concrete is low at same time strength also low when compared to conventional concrete, so an attempt made to improve mechanical properties of foam concrete by adding admixtures like Silica fume and GGBS in different percentages. In these experimental studies, the workability and compressive strengths are mentioned.
