Sleeve grouting material for connecting fabricated building steel bars
The invention discloses a sleeve grouting material for connecting prefabricated building steel bars. The sleeve grouting material is prepared from the following raw materials in parts by weight: 385 to 430 parts of cement, 80 to 105 parts of admixture, 450 to 530 parts of sand, 0.05 to 0.2 part of water-retaining agent, 0.2 to 2.0 parts of defoaming agent, 1 to 8 parts of water reducing agent, 2 to 10 parts of retarder, 1 to 20 parts of expanding agent, 1 to 20 parts of early strength agent and 115 to 145 parts of mixing water. The method comprises the following steps: weighing the raw materials according to a preset proportion, firstly adding powders into a stirrer, performing stirring for 1 minute at a low speed, performing uniform mixing, then adding water, and performing stirring for 3-5 minutes, thereby obtaining the sleeve grouting material for connecting the prefabricated building steel bars. The obtained grouting material has excellent mechanical properties.
本发明公开了一种装配式建筑钢筋连接用套筒灌浆料，由以下按照重量份计的原材料组成：385‑430份水泥，80‑105份掺合料，450‑530份砂子，0.05‑0.2份保水剂，0.2‑2.0份消泡剂，1‑8份减水剂，2‑10份缓凝剂，1‑20份膨胀剂，1‑20份早强剂，115‑145份拌合水。按照预定比例称量所述原材料，先将粉料加入搅拌机中，低速搅拌1min混合均匀，然后加水搅拌3‑5min，得到装配式建筑钢筋连接用套筒灌浆料。所得灌浆料力学性能优异。
