Influence of different curing conditions on the pore structure and the early age properties of mortars with fly ash and blast-furnace slag
In this work, the evolution of the microstructure, durability properties and mechanical strength of mortars made with commercial cements, which contain fly ash (between 21% and 35%) and ground granulated blast-furnace slag (between 66% and 80%), were studied. These mortars were exposed to three diff...

These mortars were exposed to three different environments during their hardening, an optimum laboratory condition, and two environments representing a mild Atlantic climate and a Mediterranean climate, respectively. As a reference, ordinary Portland cement mortars were also tested. The microstructure was characterized using mercury intrusion porosimetry.
