Abstract:
The aim of this experimental work was to evaluate the physical and mechanical performance of concretes steam cured at a maximum temperature of 60 °C. It explores the potential benefits of steam-cured concrete products in the precast industry that are made with different cements and with supplementary cementitious materials. All concretes had the same workability and were produced with two cements: high- early strength portland cement and blast-furnace slag portland cement. Concretes also had the addition of 10% of silica fume by mass of cement. The concretes were tested at different ages (mechanical strength, air permeability, capillary absorption and voids). The results showed that steam curing is beneficial to concretes made with blended slag cement, and silica fume addition improved the properties of steam-cured concretes.
