The invention relates to a grouting material composition particularly suitable for joining precast concrete members at low temperatures, comprising, based on the total weight of the dry composition: A) 12-50 wt% of a calcium sulphoaluminate binder; b) 3.5 to 35 wt% of high belite calcium sulphoaluminate cement; c) 1.3 to 10 wt% of calcium sulfate; and D) 0-2% by weight of an alkaline earth metal oxide or hydroxide; wherein the total amount of the three components A) to C) is from 42% to 54.5% by weight, based on the total weight of the dry composition. In addition, the invention also relates to a method for applying the grouting material composition and a connector obtained by the method.
本发明涉及一种特别适合于低温下连结混凝土预制构件的灌浆料组合物，其包含基于干燥组合物总重量计：A)12‑50重量％的硫铝酸钙胶结料；B)3.5‑35重量％的高贝利特硫铝酸钙水泥；C)1.3‑10重量％的硫酸钙；和D)0‑2重量％的碱土金属氧化物或氢氧化物；其中所述三种组分A)到C)的总量为42重量％‑54.5重量％，基于干燥组合物总重量计。此外，本发明还涉及施用该灌浆料组合物的方法以及由此获得的连接体。
