The invention belongs to the technical field of concrete waterproof additives, and particularly relates to a concrete waterproof additive. The concrete waterproof additive is prepared from the following components in parts by mass: 100-200 parts of silica fume, 50-100 parts of sodium methylsilanolate, 20-50 parts of triethoxysilane, 20 -40 parts of organic silicon water aqua, 100-200 parts of calcium carbonate, 10-20 parts of expanding agent, 10-20 parts of cross-linking agent, 20-50 parts of volcanic ash, 50-100 parts of ferric chloride and 10-20 parts of a water reducing agent. The double-expansion-source expanding agent based on the sulfate-series expanding agent and the magnesium oxide-series expanding agent is arranged, and the cracks appearing on the outer wall of the cement caused by the fact that monosulfate is used as an additive and easily reacts with calcium hydroxide and hydrated calcium chlorate in cement to generate hydrated calcium sulphoaluminate can be reduced so the compactness of concrete is improved, and the formed liquid siliceous compacting agent can preliminarily compact concrete gaps without influencing the use of the expanding agent.
本发明公开的属于混凝土防水添加剂技术领域,具体为一种混凝土防水添加剂,该混凝土防水添加剂的组成成分按照质量比重分别为:硅灰100‑200份、甲基硅醇钠50‑100份、三乙氧基硅烷20‑50份、有机硅水剂20‑40份、碳酸钙100‑200份、膨胀剂10‑20份、交联剂10‑20份、火山灰20‑50份、氯化铁50‑100份,减水剂10‑20份,本发明通过设有基于硫酸盐系列膨胀剂和氧化镁系列膨胀剂的双膨胀源膨胀剂,从而降低单硫酸盐作为添加剂,容易和水泥中氢氧化钙和水化氯酸钙反应生成水化硫铝酸钙,水泥外壁出现裂缝的数量,从而提高混凝土的密实性,形成的液态硅质密实剂,在不影响膨胀剂使用的情况下,可对混凝土的空隙进行初步密实。
