摘要：In recent development scenario, the lightweight concrete is a versatile material, which offers a range oftechnical, economic and environmental –enhancing and preserving advantage and is designed to become a dominantmaterial in the millennium. For structural application of light weight concrete, the density is often more important thanthe strength. A decreased density for the same strength level reduces the self weight, foundation size and constructioncost. Structural lightweight aggregate concrete is generally used to reduce dead weight of the structure as well as toreduce the risk of seismic damage to a structure because the seismic forces that will influence the civil engineeringstructures are proportional to the mass of those structures.In this study,structural light weight aggregate concrete was designed with the use of natural vermiculiteaggregate that will provide an advantage of reducing dead weight of structure and to obtain a more economicalstructural light weight concrete by the use of vermiculite power as a partial replacement of sand. Three mixes wereproduced with the cement content of 479kg/m3 in M30 grade and water cement ratio is 0.40. More over the group hadproportion of 0%, 5%, 10%, as vermiculite replacement.The main scope of our project is to learn and gatherknowledge of strength, and density. It may help us to get clear idea about the light weight concrete, using vermiculite.
