Special anti-sloughing liquid coagulant for foam concrete cast-in-place wall
The invention relates to the field of concrete auxiliary agents, in particular to a special anti-sloughing liquid coagulant for foam concrete cast-in-place wall. The special anti-sloughing liquid coagulant is prepared from the following components in parts by weight: 30-55 parts of polyaluminum sulfate, 5-10 parts of magnesium sulfate, 0.1-5 parts of tertiary amine, 1-5 parts of magnesium fluosilicate, 0.1-0.5 part of an amide modified polycarboxylate superplasticizer, 1-4 parts of mixed acid, 0.1-0.5 part of sodium bicarbonate, 0.1-0.5 part of hydroxypropyl methyl cellulose, 0.1-0.5 part of carboxymethyl starch ether, 1-3 parts of sodium tripolyphosphate and 400-500 parts of water. The early setting agent can shorten the initial setting time and the final setting time of the foam concrete, prevents a foam concrete wall from collapsing, avoids the bleeding phenomenon, and improves the mechanical property of the foam concrete to a certain extent.
本发明涉及混凝土助剂领域，具体为一种泡沫混凝土现浇墙体专用防塌型液体促凝剂，以重量份数计，由以下成分组成：聚合硫酸铝30‑55份、硫酸镁5‑10份、三级胺0.1‑5份、氟硅酸镁1‑5份、酰胺改性聚羧酸减水剂0.1‑0.5份、混酸1‑4份、碳酸氢钠0.1‑0.5份、羟丙基甲基纤维素0.1‑0.5份、羧甲基淀粉醚0.1‑0.5份、三聚磷酸钠1‑3份、水400‑500份，本发明早凝剂可以缩短泡沫混凝土的初凝和终凝时间，防止泡沫混凝土墙体塌模，避免泌水现象的发生，而且对于泡沫混凝土的力学性能也有一定程度的提升。
