Concrete water reducing agent composition
The invention relates to the technical field of concrete, in particular to a concrete water reducing agent composition which comprises the following materials: methylnaphthalene, sulfuric acid, polycarboxylic acid, lignosulfonate, allyl alcohol polyoxyethylene ether, unsaturated acid, sulfur trioxide, a formaldehyde solution, a caustic soda solution, an oxidizing agent and a reducing agent. The composition comprises 5-10 parts of the methylnaphthalene, 5-10 parts of the sulfuric acid, 4-8 parts of the polycarboxylic acid, 10-20 parts of the lignosulfonate, 6-10 parts of the allyl alcohol polyoxyethylene ether, 3-6 parts of the unsaturated acid, 2-5 parts of the sulfur trioxide, 3-4 parts of the formaldehyde solution, 2-3 parts of the caustic soda solution, 1-3 parts of the oxidizing agentand 1-3 parts of the reducing agent. The water reducing agent can well improve compressive strength of concrete. The water reducing agent is synthesized from the allyl alcohol polyoxyethylene ether and the unsaturated acid; the added novel polycarboxylate water reducing agent has antirust and lubricating effects, so that the mixing performance of the concrete can be improved, the corrosion of reinforcing steel bars can be prevented, the service lifetime of the concrete can be prolonged, and the use stability of the concrete can be improved.
本发明涉及混凝土技术领域，尤其为一种混凝土减水剂组合物，包括以下材料：甲基萘、硫酸、聚羧酸、木质素磺酸盐、烯丙醇聚氧乙烯醚、不饱和酸、三氧化硫、甲醛溶液、烧碱溶液、氧化剂、还原剂，其中各材料用量分别为：甲基萘5～10份、硫酸5～10份、聚羧酸4～8份、木质素磺酸盐10～20份、烯丙醇聚氧乙烯醚6～10份、不饱和酸3～6份、三氧化硫2～5份、甲醛溶液3～4份、烧碱溶液2～3份、氧化剂1～3份、还原剂1～3份，通过该减水剂能够很好的提高混凝土的抗压强度，通过烯丙醇聚氧乙烯醚和不饱和酸合成减水剂，添加新型聚羧酸减水剂具有防锈、润滑的作用，能够增加混凝土的拌合性能，同时能够防止钢筋锈蚀，延长混凝土的使用寿命，提高混凝土的使用稳定性。
