摘要：
本发明公开了一种混凝土防冻剂，由以下重量份的组分组成：聚羧酸高性能减水剂15～20份、亚甲基二萘磺酸钠5～10份、聚丙烯酰胺2～4份、丙三醇20～30份、硝酸钙5～10份、烷基糖苷6～10份、茶皂素1～1.5份、葡萄糖酸钠4～6份、松香酸钠0.3～0.6份、十二烷基苯磺酸钠0.6～1.2份、异辛醇聚氧乙烯醚0.5～0.8份、壬基酚聚氧乙烯醚0.2～0.4份、水50～70份。本发明的混凝土防冻剂能显著降低混凝土拌合物的冰点，可以保持混凝土在‑20℃下不结冰，且无氯、无碱、无氨，环境友好。
摘要（英）：

The invention discloses a concrete antifreezing agent. The concrete antifreezing agent is prepared from components in parts by weight as follows: 15-20 parts of a polycarboxylate superplasticizer, 5-10 parts of a dispersing agent NNO, 2-4 parts of polyacrylamide, 20-30 parts of glycerin, 5-10 parts of calcium nitrate, 6-10 parts of alkyl glycoside, 1-1.5 parts of tea saponin, 4-6 parts of sodium gluconate, 0.3-0.6 parts of sodium abietate, 0.6-1.2 parts of sodium dodecyl benzene sulfonate, 0.5-0.8 parts of isooctanol polyethenoxy ether, 0.2-0.4 parts of nonylphenol polyoxyethylene ether and 50-70 parts of water. The concrete antifreezing agent can reduce the freezing point of a concrete mixture obviously, can keep concrete unfrozen at the temperature of subzero 20 DEG C and is chloride-free, alkali-free, ammonia-free and environment-friendly.
