Machine-made sand anti-segregation concrete and preparation method thereof
The invention belongs to the technical field of building materials, and relates to machine-made sand anti-segregation concrete, in particular to a polycarboxylic acid water reducing agent (JHN-WR001) for the machine-made sand anti-segregation concrete, which is based on molecular design modification of the polycarboxylic acid water reducing agent and realizes the integrated functions of high water reducing, high slump retaining and high thickening of the polycarboxylic acid water reducing agent. The design key points are as follows: (2, 7-octadiene-1-yl) succinic anhydride and polypropylene glycol monobutyl ether are adopted to prepare an ester monomer, and then the ester monomer is polymerized with a methacrylic acid monomer and methyl allyl polyoxyethylene ether to obtain the high-performance polycarboxylate superplasticizer.
本发明属于建筑材料技术领域，本发明涉及一种机制砂抗离析混凝土，更为具体的是一种机制砂抗离析混凝土用聚羧酸减水剂(JHN‑WR001)，本发明基于聚羧酸减水剂分子设计改性，实现聚羧酸减水剂高减水、高保坍、高增稠一体化功能。设计要点为采用(2,7‑辛二烯‑1‑基)琥珀酸酐与聚丙二醇单丁醚到酯化物单体，后经过甲基丙烯酸单体、甲基烯丙基聚氧乙烯醚聚合得到。
