Creep and Shrinkage of High Performance Concrete

摘要

High performance concrete is a wide-ranging description of concretes havingspecial physical properties. This study considers the creep and shrinkage properties of a high performance concrete having an ultimate strength of 90 MPa. Specifically in this study, we looked at such variables as the effects of curing temperature, age at loading, and stress level. We used strain measurements taken through 120 days, along with curve-fitting techniques, to estimate the ultimate creep coefficient and ultimate shrinkage strains of the concrete. We also compared the recorded data with predictions made using ACI Committee 209 recommendations.
