Abstract

This research was conducted to study the mechanical and the physical properties of concrete mixes made of light weight expanded clay aggregates with trade name (LECA). One hundered and five concrete mixes were investigated. The aggregate used was a mixture of "LECA" and gravel with different proportions. Concrete mixes with "LECA" only or gravel only were tested for comparison. The main properties of the concrete mixes tested in this investigation were the unit weight, absorption percentage, compressive strength, flexure strength and modulus of elasticity. Bond strength between concrete and steel was also investigated. It was found that an adquate strength with reasonable unit weight and absorption percentage of concrete could be achieved by partial replacement or gravel in the concrete mix by "LECA".
