Abstract

Structural lightweight concrete is "significant in contemporary construction. This concrete provides technical and environmental benefits, so it is intended for use in the next millennium. Density is frequently more important than strength for lightweight concrete structural applications. A lower density at the same strength level reduces “self-weight”, "foundation size," and construction expenses. In addition, using lightweight concrete as opposed to standard weight concrete could provide additional benefits such as heat and sound insulation. A special type of "self-cured lightweight concrete" has been developed to utilize the voids in lightweight aggregate's water reservoirs for curing. The experimental investigation of the structural behavior of lightweight concrete as a function of concrete type and bonding was conducted. Cubes and cylinders were employed in the experimental investigation. Concrete type (normal weight concrete and lightweight concrete) and cement content (350, 400, and 450 kg/m3) were considered as test variables.Concrete type (normal weight concrete and lightweight concrete) and cement content (350, 400, and 450 kg/m3) were considered as test variables.
