The relation between the compressive strength and modulus of elasticity of concrete with crushed brick and roof-tile aggregates
This paper presents the results of experimental research into the effect of brick and roof-tile aggregates on the values of the modulus of elasticity of concrete made with crushed brick and roof-tile aggregates. The main purpose of this paper is to compare the formulae given in the code provisions for estimating the concrete elastic moduli for lightweight and normal weight concretes with experimentally obtained values. Sixty-two different concrete mixtures including crushed brick and roof tiles were made and experimentally tested. The differences between the empirical and experimental static moduli of elasticity are shown. In addition, formulae for the calculation of the static modulus of elasticity over compressive strength are shown, and compared with an experimentally estimated formula. As a result of this investigation, a universal equation for estimating the static modulus of elasticity over compressive strength for concretes with crushed brick and roof-tile aggregates is proposed.
