Experimental studies on shrinkage of high-performance concrete
This article outlines experimental and numerical studies on shrinkage of high-performance concrete (HPC). Carbonation shrinkage especially may introduce surface cracking in concrete, which affects the durability. In order to study shrinkage, cylinders of eight qualities of HPC were investigated. Parallel studies on autogenous shrinkage, drying shrinkage, hydration, internal relative humidity, and strength were carried out. Previous research in the field is summed up. Mechanisms of carbonation shrinkage by modeling correlations to the composition of the HPC and the physical properties are presented. The results indicate that carbonation shrinkage may be avoided by addition of silica fume. The project was carried out from 1992 through 1996.
