Abstract

Abstract

The whole-course of autogenous shrinkage deformation of high performance cement based materials was in vestigated by stages with the combining of volume measurement and length measurement.The effects of the type of mineral admixtures,including fly ash and ground blast furnace slag,addition rate and fineness on the autogenous shrinkage were studied.The mechanism was discussed on the basis of capillary tension theory.
- mineral admixtures,
- high performance cement-based material,
- autogenous shrinage
