In the present scenario in the world, the cost and environmental pollution of cement are very high which is obtained from the cement industries. Alternately we want to decrease the cost and environmental pollution by adding waste industrial materials. Among the many types of admixtures, Perlite Powder (PP) is a material with very low thermal conductivity & GGBS from industries which can be made blended concrete with perlite and GGBS powder. For the strength purpose, partial replacement of cement is carried out by GGBS at 20%. In this work different tests have been performed on M30 grade of concrete like compression test, tensile test, water absorption test. The Present work describes the comparative study of partial replacement of Perlite and GGBS powder in cement. And the Compression and Tensile tests were performed for 7days and 28days and 56 days of curing at 4% PP + 20% constant of GGBS, the compressive strength and tensile strength both are observed to be increased by 0.54% and 1.68% respectively as compared to the conventional concrete of M30 grade. And also did water absorption at 1050C and by taking of perlite powder in Mix which controls the thermal properties of concrete.
