Abstract : Ground granulated blast-furnace slag GGBS is a common by-product used for decades in the cement and concrete industry, and having beneficial effects on environmental properties and durability of concretes. However, GGBS reacts less rapidly than cement and the short-term compressive strength of GGBS-concretes are usually lower than the ones of Portland cement concretes. The aim of this paper is to test the efficiency and evaluate the synergic effect of combining different activation routes fineness of Portland cement and GGBS, use of chemical activation, and application of thermal cycles on short-term compressive strength of GGBS-Portland cement-based materials. Results showed that the simultaneous use of all activation routes allowed blended cement with GGBS to achieve almost the same initial mechanical characteristics than Portland cement.
