Beschreibung
Zusammenfassung:The present invention relates to an improved mineral binder composition comprising: a mineral binder comprising at least 30 weight-% slag, based on the weight of the mineral binder, an activator for the hydration of the slag consisting of or comprising calcium hydroxide and a co-activator consisting of or comprising at least one salt selected from the group consisting of lithium carbonate, lithium sulfate and sodium carbonate. The improved mineral binder composition shows reduced setting time and increased early strength. 本发明涉及一种改进的矿物粘结剂组合物，其包含：-包含基于矿物粘结剂重量计至少30wt％的炉渣的矿物粘结剂，-用于炉渣水合的活化剂，其包含氢氧化钙或由氢氧化钙组成，和-助活化剂，其包含至少一种选自碳酸锂、硫酸锂和碳酸钠的盐或由至少一种选自碳酸锂、硫酸锂和碳酸钠的盐组成。该改进的矿物粘结剂组合物显示了减少的固化时间和提高的早期强度。
