An alternative low-energy alinite-chlormayenite clinker was produced and its hydration with different gypsum content was studied. The clinker was produced at 1225 °C using reagent-grade materials in an electric kiln with alinite, larnite, and chlormayenite content of 48, 24, and 16 wt%, respectively. The hydration kinetics of the clinker with different gypsum additions (0,10, 20, and 40 wt%) did not have a distinct induction period, and the hydration was faster than Portland cement. Alinite was in general more reactive than chlormayenite. In the presence of a limited amount of gypsum (10 and 20 wt%), alinite consumed gypsum to form ettringite within the first hour of hydration, and both alinite and chlormayenite formed Friedel's salt after gypsum was exhausted. Sufficient gypsum availability (40 wt%) slowed down the dissolution of alinite and chlormayenite for the first hour of hydration but enabled both chlormayenite and alinite to form ettringite.

褐铁矿-氯铁矿熟料的生产及其随石膏含量增加的水化行为


生产了一种替代的低能褐藻酸盐-氮化霉素熟料，并研究了其在不同石膏含量下的水化作用。熟料是在 1225 °C 下使用试剂级材料在电窑中生产的，褐铁矿、钙石和氮化石含量分别为 48%、24 和 16 wt%。添加不同石膏 （0、10、20 和 40 wt%） 的熟料的水化动力学没有明显的诱导期，水化速度比波特兰水泥快。褐藻酸盐通常比氮化石更具反应性。在有限量的石膏（10 和 20 wt%）存在下，褐藻石在水化的第一个小时内消耗石膏形成钙石，石膏耗尽后褐藻石和氮化石都形成了弗里德尔盐。足够的石膏可用性 （40 wt%） 在水化的第一个小时内减慢了钙镁石和氮化石的溶解，但使氯铁矿和钙镁石都能形成钙石。
