High Density Concrete Using Different Aggregates With Addition of Geo Polymers and Rice Husk Ash

S Cement Concrete is one of the most important material used in construction, as it provides good ductility and can be moulded into any shape. Normal cement concrete holds a very short tensile strength, limited ductility and little resistance to cracking. It has been initiated that various types of fibers added in exact percentage to concrete expands the mechanical properties, durability and serviceability of the structure. The main aim of the study is to study the strength of M20 grade of concrete by adding rice husk ash and barite comparing with conventional concrete. The admixtures are added from replacing cement with fly ash and GGBS at 25%, 50% & 75% to the volume of cementious material. The mechanical properties namely compressive strength, split tensile strength were carried for concrete specimen at different age level and the basic test was conducted for cement, coarse aggregate and fine aggregate.
