Abstract

The influence of two different curing conditions (in water at 27°C, and in air at 15°C and 60% relative humidity) on the mechanical and durability properties of fly-ash cement pastes and mortars are studied. Cement pastes and mortars at two water/cement or binder ratios were prepared in the laboratory and tested for compressive strength, chloride and water penetration. The mercury intrusion porosity of the samples is monitored to provide mechanistic explanations for the measured results. The results show that fly ash has significantly different influence on the strength, porosity and durability parameters of cement pastes and mortars when the cementitious materials are subjected to different curing conditions.
