Abstract:
This work proposes a methodology to evaluate the elastic modulus of lightweight-aggregate concretes. To this end, an analytical formula is achieved by curve-fitting experimental results from 135 concrete samples made of 45 different mixtures. The validation of the proposed methodology is carried out by applying the obtained analytical formula to another set of 90 concrete samples made of 30 different mixtures. The results are fair and suggest that the proposed methodology could be extended and applied.
