Abstract
This research presents a method for the estimation of the elastic modu lus of lightweight aggregate. An experimental study was carried out to measure the elastic modulus of lightweight concrete in function of th e amount of lightweight aggregate. The elastic modulus of lightweight aggregate was obtained using composite theory models applied to the ex perimental data. Based on the Mori-Tanaka model, the elastic modulus o f three different types of lightweight aggregates ranged from 12.5 to 19.6 GPa. These values are in agreement with experimental results repo rted in the literature.
