- •
Effect of gypsum type on properties of cementitious materials was investigated.
- •
Two different types of cement, which prepared from the same clinker, were used.
- •
However, cements were contained calcium sulfate hemihydrate or dihydrate as retarder.
- •
Fresh properties of mixtures were negatively affected when cement-containing hemihydrate was used.
- •
However, hemihydrate utilization had a positive influence on the early compressive strength.
