Abstract:This paper presents results of a study conducted to identify the drying shrinkage and compressive creep of high performance/high strength concrete (HP/HSC).The study included an experimental program and a comparison of available analyticalmodels for predicting creep and shrinkage. Results from creep and shrinkage tests performed on different mixes (with compressive strengths up to 90 MPa) were compared with those from prediction models available in the literature. The effects of pozzolanicmaterials the creep and shrinkage were also investigated. Results show that while fly ash increases the compressive creep of concrete, silica fume decreases it. Furthermore, thedrying shrinkage of silica fume concrete is higher than fly ash concrete. Adding fly ash could reduce the drying shrinkage of silica fume concrete. Moreover, current creep and shrinkage prediction models need to be revised for the HP/HSC mixture.
