Experimental study on fly ash bricks with addition of cement

Abstract

In this paper, effort has been made to study the behavior of Fly ash brick by taking different proportions of Fly ash, Cement, Gypsum, Lime, Sand and Stone Dust. Ten different mixes of bricks have been designed. In five mix materials like: Fly ash, Lime, Gypsum, Sand and with different % of Cement, such as 2.5%, 5%, 7.5%, and 10%. In other mixes Stone dust has been replaced instead of Sand. Various tests such as Compressive Strength Test, Water Absorption Test were performed in order to have compression with conventional bricks. The result shows the variation of Compressive Strength for different mix proportions of materials mentioned earlier at different curing ages.
