Early-strength slag-based cementitious adhesive
The present invention provides exemplary methods and additives for the manufacture of cementitious adhesives comprising predominantly finely ground granulated blast furnace slag (GGBFS), having excellent 24 hour strength, preferably with little or minimal amount of ordinary Portland cement (OPC). Since OPC manufacturing involves release of carbon dioxide into the atmosphere, the use of GGBFS-based adhesive compositions contributes to enhancing sustainable practices in the construction industry and minimizing strength loss due to the absence of OPC. Strength in a GGBFS adhesive composition is enhanced by a combination of an alkaline earth metal activator and a strength enhancing component comprising a dispersant and a secondary activator.
本发明提供用于制造水泥质粘合剂的示例性方法和添加剂，所述水泥质粘合剂主要包含磨细粒化高炉矿渣(GGBFS)，具有优异的24小时强度，优选具有很少或最低量的普通波特兰水泥(OPC)。由于OPC制造涉及向大气中释放二氧化碳，使用基于GGBFS的粘合剂组合物有助于提升建筑工业中的可持续性实践并使OPC缺失带来的强度损失最小化。通过碱土金属活化剂与包含分散剂和辅助活化剂的强度增强组分的组合增强GGBFS粘合剂组合物中的强度。
