摘要：

In this work the effect of curing temperature (20, 40 and 60 degrees C) on mechanical strength of cement paste with different proportion of granulated blast-furnace slag (0 to 80 %), is evaluated. Pastes were prepared with water/cementitious material (w/cm) ratio equal 0,40. The evolution of hydration was determined following the evolution of hydration products using XRD analysis and evaluated the content of non evaporable water. Mechanical strength was evaluated trough with central composite experimental design. When increase the content of granulated blast-furnace slag and curing temperature, the results shows that mechanical strength and non evaporable water increase, while the calcium hydroxide content decrease.
