Abstract

Concrete is quickly utilizing building material all through the world. Concrete is utilized as a part of immense sums since it is just and to a great degree great building material. In numerous spots of the world the temperature is rising step by step. Now-a-days because of steady sand mining the regular sand is draining at a disturbing rate. For this situation fine total is mostly substitution of vermiculite. Utilization of vermiculite in solid it will upgrade the shrinkage and break protection, imperviousness to fire and decreases natural effect and furthermore diminish the cost. In this present study, an attempt has been made to study the mechanical properties of M20 grade concrete with different percentages at a range of 10%, 20%, 30% and 40% as partially replacement with vermiculite to the total weight of fine aggregate along with mineral admixtures like Rice Husk Ash is replace with cement by various percentages i.e., 2%, 4% and 6% and silica fume as adding of 5%, 10% and 15% by weight of cement. It has been experiential that the required strengths are achieved at optimum percentage of compressive strength i.e. 10% silica fume is addition and 4% Rice Husk Ash replacement by weight of cement and optimum percentage of split tensile strength i.e. 10% silica fume is addition and 4% Rice Husk Ash replacement by weight of cement. Water cement ratio is 0.45.Water cement ratio is put constant for all trail mixtures.
