Experimental Study on Effect of Partial Replacement of Jhama Bricks as Coarse Aggregate in Concrete

The concrete is very useful material and now a days it is not only used in the building construction work but it is also useful for the construction of the bridges, roads, dams and other important structures. The concrete is a composite material and conventional concrete is made of cement, fine aggregate, coarse aggregate and water. Since the use of concrete is very large and day by day the cost of the conventional concrete material also rises. So, it is advantageous to use the alternative materials for making the concrete. This project focuses on the coarse aggregate in concrete. In this project Jhama brick or over burnt brick is used to replace the coarse aggregate partially. This material was chosen because of their availability also possesses higher strength between 120 to 150 Kg/cm2. The jhama brick is available from brick manufacturing area. This project presents the effects of jhama class brick inclusion on the mechanical properties of jhama class brick based concrete used partially replace, ent jhama class brick to coarse aggregate ratios of 15%, 20%, 25% in M25 grade of concrete.
