An Experimental Investigation on Hybrid Geopolymer bricks by using Fly Ash, GGBS, Silica Fume and Kadapa Slab powder

Brick is the oldest building material. It is a standard sized weight bearing unit. The earliest bricks were dried which are formed from clay or mud. During 2007 the new fly ash bricks were created using by products from coal plants. A sustainable development is an important task to the cement industry. To avoid cement as a huge construction material to reduce the environmental issues, replaced with Fly ash, GGBS, Silica fume, Kadapa slab powder. For bonding polymers, limited water content is used. Hence, resulting hybrid geo-polymer brick with multi-material combination is effective. In this experimental approach, initially we were considered 75% and 25% Fly ash and GGBS respectively as a base and then varied silica fume and kadapa slab powder ranging from 2 to 5% in GGBS. Mechanical properties of the materials are giving effective values to replace. Through compressive strength results we can find optimum proportions based on silica fume and kadapa slab powder.
