PRESSURE EXERTED ON FORMWORK AND EARLY AGE SHRINKAGE OF SELF-COMPACTING CONCRETE

Abstract

Self-compacting concrete (SCC) is a flowable type of concrete where minimum energy is required to form a structural component. The high flow of SCC enables reduction in the number of workers, casting time, noise pollution and elimination of vibration. Special mix design and the flowing nature of the concrete can change early age properties such as the lateral pressure on formwork and shrinkage characteristics. This paper presents the background to SCC and discusses in detail the main aspects related to formwork pressure and early age shrinkage of current SCC formulations
