Abstract – Structural low density aggregate Concrete has an ability to reduce the self weight of the structure as well as reduces the risk of earthquake damages to a structure because earthquake forces are proportional to mass of the structure. In Design of concrete structures, low density concrete plays a prominent role in reducing the density and to increase the thermal insulation. These may relate to both structural integrity & serviceability. For structural application of low density concrete, the density is often more important than the strength. A decreased density for the same strength level reduces the self-weight, foundation size and construction costs. Low density aggregates have high porosity, their resistance to chloride penetration is better than normal weight concrete because pores are not interconnected. Exfoliated vermiculite is studied, it 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 utilisation of silica based materials as a building material. Structural low density aggregate concrete is an versatile material, which offers a range of technical, economic and environmental-enhancing. Structural low density aggregate concrete was designed with the use of expanded perlite aggregate, expanded vermiculite aggregate,that will provide an advantage of reducing dead weight of structure and to obtain a more economical structural low density concrete by the use of these materials as a replacement of the coarse aggregate.
