摘要：As we know that Foam concrete has been successfully used and it has gained popularity due to its lower density than normal concrete. Globally the construction activities are rapid and using huge amount of fine aggregate and cement. Due to continuous usage of large amount of sand and cement we are creating natural imbalance by CONTINUOUS mining of sand, lime etc., from natural resources, which causes many natural hazards and become threat to humans. As a responsible citizen of world everyone think to stop the usage of sand and cement in huge quantity for infrastructural activities. Fly ash is one alternative solution as a partial replacement of sand and cement with Alccofine. In this investigation we are replacing fine aggregate with fly ash and cement with Alccofine by usage of Using additive materials in foam concrete which provides not only workability, strength but also reduce overall cost. As reducing the quantity of sand and cement in foam concrete we conserve Green House effect and also other raw materials used for cement. Foam concrete produced with uniform distribution of air bubbles thoughout the mass of concrete. The density of foam concrete is a function of the volume of foam added to the slurry and the strength decreases as decrease in densities. This experimental investigation was designed for density of 800 kg/m3. This study was compiled in determination of workability, plastic density, water absorption and compressive strength of foam concrete. The test specimens has been casted and tested at the age of 7,14 and 28 days.
