One-part geopolymer cement from slag and pretreated paper sludge (2018, background): “The increase in drying shrinkage at higher paper sludge levels is consistent with the literature data on carbonate mineral addition to metakaolin (Yip et al., 2008).”
Properties of alkali activated slag-fly ash blends with limestone addition (2015, background): “Besides, it should be noted that the dissolution of Ca from calcium carbonates in alkali activated system was actually confirmed by [33]; also the satisfying surface binding between the limestone powder and alkali activated materials was suggested in the previous study [32].”
Evolution of binder structure in sodium silicate-activated slag-metakaolin blends (2011, background): “any variation with the time of curing, indicating that this compound is formed from the weathering of unreacted slag and is not involved to a significant extent in the alkali-activation process, as has been observed previously for low levels of calcite added to an alkali-silicate activated MK binder”
A novel method to produce dry geopolymer cement powder (2016, background): “(1) and (2) and secondly, the remaining calcium carbonate from the reaction acts as a filler material which decreases porosity and increases the compressive strength of activated slag [29,30].”
