Abstract

Over 5% of global CO2 emissions can be attributed to Portland cement production. As demand for construction material increases day by day there is an urgent need of identifying and alternative construction material. In atmosphere 90% of CO2 is emitted due to production of cement this can be rectified by replacing some other different supplementary cementations material (SCM) instead of cement GGBS has replaced instead of cement which will reduce the waste in environment and vermiculite is added instead of sand partially. These industrial waste and agriculture byproduct such as GGBS, Vermiculite, etc., can be used as cementing materials because of their pozzolanic behavior, which otherwise required large tracts of lands for dumping. Vermiculite is used as a filler material because of its low bulk density, high refractoriness, low thermal conductivity and adequate chemical inertness. All along vermiculite has high amount of silica content. Thus effective utilization of silica based materials as a building material. Presently, vermiculite is used for its light weight in the construction industry as a filler material above the deck slab. The special characteristics and usage of this material would decrease the structural weight can be decreased. Considering some other characteristics it is quite good material if it is replaced partial form gives better results. This investigation examines the physical and chemical parameters and influence that make in concrete. The GGBS is replaced 10%, 20%, 30%, 40% and 50% and vermiculite 20%, 40%, 60%, 80% and 100% respectively.
