Approximate elastic moduli of lightweight aggregate

Yang, C.C.

This study presents a method for the estimation of the elastic modulus of lightweight aggregate. In order to investigate the elastic modulus of aggregate and the effect of aggregate content on the elastic modulus of lightweight concrete, cylindrical specimens with different volume ratios (volume ratio of coarse aggregate/total aggregate) and various water/cement ratios were cast and tested. Both single inclusion and double inclusion models were applied to predict the elastic moduli of two-phase and three-phase cement-based composite materials, respectively. The elastic moduli of sand and coarse aggregate were derived from the experimental results using the theoretical models.
