Compression-resistant concrete and preparation method thereof
The invention relates to compression-resistant concrete and a preparation method thereof. The compression-resistant concrete is composed of cement, sand, water, a porous aluminum-containing material, calcium sulfate whiskers, an SE-10 emulsifier, coal ash and a surface modifier. The porous aluminum-containing material is prepared through reaction of aluminum ash, water, acrylamide, methylene bisacrylamide, a 184 photoinitiator, the SE-10 emulsifier, urethane acrylate and epoxy acrylate. The calcium sulfate whiskers are prepared from waste polyester fibers, a calcium acetate aqueous solution, dilute sulphuric acid, polyacrylamide, polyvinyl alcohol 1788 and an SE-10 emulsifier through a reaction. The surface modifier is prepared from aliphatic polyurethane acrylate, hydroquinone, triethylamine, maleic anhydride, fumed silica, ethylene diamine tetraacetic acid tetrasodium salt, cumene hydroperoxide, hyperbranched polyester acrylate, pentaerythritol tetraacrylate, polyethylene glycol methacrylate, a modified epoxy acrylate oligomer and an SE-10 emulsifier through a reaction. The compression-resistant concrete provided by the invention has excellent compression resistance.
本发明涉及一种抗压型混凝土及其制备方法。所述抗压型混凝土由水泥、砂子、水、多孔含铝材料、硫酸钙晶须、SE‑10乳化剂、煤灰和表面改性剂组成，所述多孔含铝材料由铝灰、水、丙烯酰胺、甲叉双丙烯酰胺、184光引发剂、SE‑10乳化剂、聚氨酯丙烯酸酯和环氧丙烯酸酯反应制得，所述硫酸钙晶须由废弃涤纶纤维、乙酸钙水溶液、稀硫酸、聚丙烯酰胺、聚乙烯醇1788和SE‑10乳化剂反应制得，所述表面改性剂由脂肪族聚氨酯丙烯酸酯、对苯二酚、三乙胺、马来酸酐、气相二氧化硅、乙二胺四乙酸四钠、异丙苯过氧化氢、超支化聚酯丙烯酸酯、季戊四醇四丙烯酸酯、聚乙二醇甲基丙烯酸酯、改性环氧丙烯酸酯低聚物和SE‑10乳化剂反应制得。本发明提供的抗压型混凝土具有优异的抗压性能。
