Effect of curing conditions on the pore solution and carbonation resistance of alkali-activated fly ash and slag pastes

The effect of curing conditions (sealed and unsealed) on the pore solution composition and carbonation resistance of different binary alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) pastes is investigated in this study. The studied mixtures were with FA/GBFS ratios of 100:0, 70:30; 50:50, 30:70, 0:100. Ordinary...

CO2 binding capacity of alkali-activated fly ash and slag pastes

Quantification of the CO2 binding capacity of reinforced concrete is of high<br/>importance for predicting the carbonation potential and service life of these structures. Such information is still not available for alkali activated materials that have received extensive attention as a sustainable substitute for ordinary Portland cement (OPC)...
