Abstract
The dead load of any structure varies depending on the type of bricks and its weight. Due to the increased numbers of high rise buildings, lighter materials than normal clay bricks are preferred. Fly-ash bricks are more popular presently since it weighs 28% less than clay bricks as well as shows higher strength .The strength is higher by 25% than commonly available bricks. Besides strength other characteristics such as absorption capacity, modulus of rupture, initial rate of absorption, durability and bond strength. The values thus obtained from the test shows excellent results as compared to that of brick clay. The latest type of bricks has been given the name fly-ash bricks. The key objective of the paper is to study the strength of fly ash brick using different material proportion and also to improve the compressive stress and also to determine the durability along with stability of the bricks.
