Compressive strengths of concretes containing Portland cement (10 to 100%),
slag ( 0 to 90%) and gypsum ( 0 to 40%) at different periods were determined.
Results show that cements having good strength can be made from mixtures containing
10% Portland cement, 20% gypsum and 70% slag. Mixtures containing
clinker and gypsum in higher Proportions also give good strength at la:ter ages.
Mixtures containing both clinker and gypsum in high proportions but slag in low
proportion show unsoundness.
