Physico-mechanical and microstructural properties of rehydrated blended cement pastes
Abstract
This study aims to investigate the effect of high temperatures of up to 1200 C and rehydration on the mechanical properties, microstructure and phase composition of blended cement pastes prepared from Portland cement (PC), granulated blast furnace slag (GBFS), high-temperature fly ash (FA) and ground limestone (GL). It has been found that the heating process induces a reduction in bulk density, flexural and compressive strength. The proportion of pores with a diameter higher than 0.1 micrometer increases with increasing temperature. The addition of GBFS or FA improves the strength properties of dehydrated cement paste (DCP), but this effect was not observed after rehydration. Cement paste with added GBFS has the best resistivity to high temperatures, but after rehydration, GL cement paste shows better mechanical properties.
