Reduction type concrete high-efficiency water reducing agent
The invention relates to the technical field of concrete admixtures, in particular to a shrinkage-reducing concrete high-efficiency water reducing agent. The reducing agent comprises 40-50 parts of polyether macromonomer powder, 12-18 parts of sodium lauryl sulfate, 9-16 parts of hydrated silica and 7-12 parts of zeolite powder. Due to the fact that a capillary pipeline is formed between aggregate and an admixture in concrete, shrinkage between the aggregate and the admixture is caused under the action of surface tension of liquid in the capillary pipeline, and the use effect of the concrete is affected. Therefore, the silica hydrate is wrapped by the zeolite powder through the viscose arranged on the silica hydrate, the reaction rate of the zeolite powder in the concrete is promoted through the flaky structure of the silica hydrate, and after the silica hydrate is put into the concrete to be mixed, the flaky silica hydrate is crushed through interaction among aggregates in the concrete, with the reaction of the cellulose gum and the zeolite powder in the liquid, the cellulose gum is filled into the gap between the aggregate and the admixture so as to weaken the shrinkage degree of the concrete, such that the application effect of the shrinkage type concrete high efficiency water reducing agent is improved.
本发明涉及混凝土外加剂技术领域，具体涉及一种减缩型混凝土高效减水剂，包括聚醚大单体粉体40‑50份、月桂醇硫酸酯钠12‑18份、水合硅石9‑16份和沸石粉7‑12份；由于混凝土中骨料与掺合料间形成的毛细管路，在其中液体的表面张力作用下，导致骨料与掺合料间的收缩，而影响到混凝土的使用效果；故此，本发明通过设置在水合硅石上的纤维胶，使沸石粉将其包裹起来，通过其片状结构促进了沸石粉在混凝土中的反应速率，在其投入混凝土中进行拌和后，混凝土内部骨料间的相互作用，使片状的水合硅石产生破碎，配合沸石粉在液体中的反应，使得纤维素胶填充至骨料与掺合料间的空隙中，削弱混凝土的收缩程度，从而提升了减缩型混凝土高效减水剂的应用效果。
