DescriptionThe creep and shrinkage properties of Self Consolidating Concrete (SCC) containing supplementary cementitious material such as silica fume (SF), Fly Ash (FA) and slag (SL), are based on limited research on normal or high performance concrete. Thus, there is a need for comprehensive testing and evaluation of self consolidating concrete mixes containing supplementary cementitious material to determine their mechanical and physical. The objective of this research is to study the effect of different cementitious material on the creep and shrinkage behavior of structures made with SCC. Twelve self consolidating concrete (SCC) mixes were considered for the experimental program. Different
percentages of FA, SF, SL, and Type I Cement were incorporated into the mix designs. Concrete specimens were fabricated and tested for their compressive strength, tensile strength, elastic modulus, shrinkage and creep. Existing creep and shrinkage prediction models were also studied and evaluated for SCC.
The study found that the addition of SF and SL decreased the specific creep, whereas the
addition of fly ash had no influence on specific creep. In addition, a reduction in the cement content helped to reduce the specific creep. Drying shrinkage was not affected by the increase in silica fume content, and it slightly decreased with an increase in fly ash and slag. A reduction in cement content also resulted in a reduction in shrinkage strain. Based on different methods of comparison, the CEB, GL2000 and Dilger models predicted shrinkage well, while the B3, GZ and Sakata models predicted creep well.
