Abstract:
Concrete is second most using material in the world today. Attributing mainly to low cost of materials and maintenance. Much advancements in concrete technology have been occurring from last three decades. Light weight concrete (LWC) is formed by light weight aggregates (Vermiculite) Light weight vermiculite is one type of light weight concrete. Vermiculite is a light weight and cheap product because of its thermal resistance has become a valuable insulating material. The density of these concrete varies from 750 Kg/m3 to 2050 kg/m3. This less density enhances reduction of dead load which results much economical design of structures. Effect of fly ash as partial replacement for cement in light weight vermiculite concrete were investigated by replacing 0%, 10%, 20% and 30% of cement content with fly ash, in which up to 20% shows optimum results and a significant increase in density and compressive strength of light weight vermiculite concrete..
Keywords: Light weight concrete (LWC), Vermiculite and Light weight aggregate.
