Lightweight Concrete - an overview | ScienceDirect Topics

Elastic modulus of lightweight concrete with PVC aggregate was studied by Kou et al. (2009).Their results indicate that elastic modulus is reduced with an increase in PVC content. The 28-day elastic modulus were reduced by 6.1%, 13.8%, 18.9%, and 60.2% for PVC aggregate content of 5%, 15%, 30%, and 45%, respectively. This elastic modulus degradation is attributed to: (a) lower elastic modulus ...
