"Influence of Slag Type and Replacement Level on Strength Elasticity, Shrinkage and Creep of Concrete"

Ten blended slag-cement concretes, made with typical slags from 4 different countries were compared with a control ordinary Portland cement concrete. Concretes were compared on the basis of equal mass proportions of cementitious materials, aggregates and water. Average strength, elasticity and creep are quantified relative to the corresponding properties of the control concrete. The influence of type of slag on concrete properties is inconsistent and small. The influence of replacement level on strength and creep is time-dependent. For water-stored mature concrete, slag enhances the secant modulus of elasticity, but the opposite occurs for dry-stored concrete.
