Study of Light Weight Bricks by using Cement Sand Fly Ash and Foaming Agent

The use of light weight concrete is found to be advantageous in the self-weight of any structure. Self-weight of foamed light weight concrete is lighter than normal concrete nor brick. It became a sweet solution in civil industry. Foam concrete is a vast majority of concrete containing no large aggregates, only fine sand and with extremely light weight materials containing cement, water and foam. It can be considered relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase. Application of foamed light weight concrete on the wall of high rise building will decrease structural load while lower structural load the structural dimension will significantly decrease and construction cost too. Our project represent that foam concrete is effective sustainable material for construction with use of effective cost in foam concrete as replacement of coarse aggregate material. Compressive strength, density test and water absorption test that have been performed with various proportion of foaming agent for 0.1%, 0.2%, 0.3%. Comparison used 1 cement: 1 aggregate. Aggregate consist of sand & fly ash added material 0%, 15%, 30%, 45%, 60% & 75% by weight of sand. Cement water factor 0.35% & foam 30%, 40% & 50% of light weight concrete volume. Cylinder sample dimensions are 75mm in dia and 150mm in depth. The study concludes an optimal mix design with 10% fly ash along with 10% stable foam to create light weight foamed concrete brick with fly ash.
