Abstract

This research investigates the drying shrinkage of non-sintering cement(NSC) matrix added phosphogypsum(PG) and waste lime(WL) to granulated blast furnace slag(GBFS) as sulfate and alkali activators with various curing condition. The experimental results are follow: When the moisture is fully supplied at the early curing age, there is effect which carries out abundant generation of the ettringite which is an expansion nature mineral, and compensates for contraction with a chemical prestress concept.
