Polycarboxylate superplasticizer, high stone powder concrete and preparation method of high stone powder concrete
The invention relates to a polycarboxylate superplasticizer, a high stone powder type concrete and a preparation method of the high stone powder type concrete. The concrete contains the polycarboxylate superplasticizer. Wherein the polycarboxylate superplasticizer comprises the following components: an unsaturated polyether, an oxidizing agent, a reducing agent, acrylic acid, a catalyst, a pH regulator and water, and the molecular weight of the unsaturated polyether is 2000-5000. Compared with the prior art, the concrete provided by the invention has the advantages of high stone powder content, good concrete compactness, good water reducing and slump retaining effects, and the concrete mechanical strength is not influenced.
本发明涉及一种聚羧酸减水剂、高石粉型混凝土及其制备方法，该混凝土含有所述聚羧酸减水剂。其中，聚羧酸减水剂包括以下成分：不饱和聚醚、氧化剂、还原剂、丙烯酸、催化剂、pH调节剂和水，所述不饱和聚醚的分子量为2000～5000。与现有技术相比，本发明的混凝土中石粉含量高，混凝土致密性好，且具有良好的减水与保坍效果，且不会影响混凝土的力学强度。
