Shrinkage and Fracture Properties of Semiflowable Self-Consolidating Concrete
Publication: Journal of Materials in Civil Engineering
Volume 23, Issue 11
Abstract
Shrinkage behavior and fracture properties of five semiflowable self-consolidating concrete (SFSCC) mixes are studied, and their results are compared with those of conventional pavement concrete. In the study, prism tests were employed to evaluate concrete free shrinkage behavior. Restrained ring tests were performed to assess concrete cracking potential. In addition, unrestrained ring tests were conducted and compared with the restrained ring tests. Compressive strength, splitting tensile strength, elastic modulus, and notched beam fracture properties of the concretes were tested at 1, 3, 7, 14, and 28 days. The results indicate that the rates of shrinkage of SFSCCs are generally higher than those of conventional pavement concrete. Compressive strength, splitting tensile strength, and critical stress intensity factor of SFSCCs are comparable to those of conventional pavement concrete, but elastic modulus of SFSCCs is lower than that of conventional pavement concrete. With a higher shrinkage stress-to-fracture strength ratio, SFSCC mixes have higher potential for shrinkage-induced cracking than conventional pavement concrete. The use of a clay additive, purified magnesium alumino silicate, further increases the rate of SFSCC shrinkage.

Acknowledgments
The present study is a part of the research project Self-Consolidating Concrete—Applications for Slip Form Paving, which is pool-funded by five state departments of transportation (Iowa, Kansas, Nebraska, New York, and Washington States), some concrete admixture companies, the Federal Highway Administration (FHWA), and the National Center of Concrete Pavement Technology (CP Tech Center). The authors gratefully acknowledge this research sponsorship. The project is conducted through collaboration between the CP Tech Center, Iowa State University (ISU) and the Center for Advanced Cement Based Materials (ACBM), Northwestern University (NU). Valuable suggestions from Dr. Peter Taylor at the CP Tech Center and discussions with Dr. Surendra P. Shah at ACBM on the shrinkage tests are earnestly appreciated.
