Abstract:Ten blended slag-cement concretes made with typical slags from four countries are compared with a control ordinary portland cement concrete. The slags replaced 30 to 70 percent of cement by mass. Concretes are 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. Compared with OPC concrete, slag-cement concrete has a similar or greater long-term strength, similar shrinkage, lower basic creep, and similar or lower total creep.
