: Lightweight concrete has been wide utilised in several structural applications and its consumption grows each year on a worldwide base. The cause for this is often that mix treatment of light-weight concrete has several benefits. These include: a discount within the loading of the structure, that minimizes the size of structural members; the assembly of lighter and smaller pre-cast parts with cheap casting, handling and shipping operations; the look of extra space as a result of the diminution in size of the structural members; a decrease within the peril of earthquake damage; and enlarged thermal insulation and flame resistance. In India, among the multiple construction applications, masonry structures type the best proportion of the uses of typical burnt clay bricks, ash bricks, hollow concrete block, that have several drawbacks (like an excellent weight, non-uniform form and size, low thermal insulation and fireplace resistance etc.), which will be improved by mixed treatment of light-weight concrete. the employment light-weight concrete, provides improved thermal insulation and flame resistance, thereby it's thought of a good approach not solely in fireplace protection however conjointly in reducing the U-values (it’s the live of warmth passing through a structural element) of structures . In this dissertation Foam Concrete blocks are cast with 65% of Fly ash and 35% of cement with foam content 1.5% of total weight and to increase its strength sand and Quarry Fine is added in their composition which replaces fly ash up to 30% at an interval of 5%. To check properties of these cellular lightweight concrete (FC) block test like compressive strength, density and water absorption is performed in the lab.
