Effect of Modulus of Elasticity on Creep Prediction of High Strength Concrete Containing Pozzolans

Abstract

The focus of this study is investigating the sensitivity of each creep prediction model wjen using various modulus of elasticity equations. Nine high strength concrete (HSC) mixes containing pozzolans were made and tested in the laboratory. The mixes consisted of three mixes with varying percentage of silica fume, three mixes with varying percentage of fly ash, and three mixes with different combination of silica fume and fly ash. Data on elastic modulus from these mixes as well as from other tests have been used to form the basis of developing an elastic modulus equation for HSC. Three creep prediction models are considered in the study.
