Super wear-resistant concrete and preparation process thereof
The invention relates to super wear-resistant concrete and a preparation process thereof, and belongs to the technical field of concrete. According to the invention, a silane coupling agent with double bonds is creatively used as a modifier, and the silane coupling agent is subjected to hydrolytic polycondensation and then is copolymerized with methyl allyl polyoxyethylene ether and acrylic acid on the basis of free radical polymerization, so that the silane modified water reducer containing silanol bonds is prepared; then a polyvinyl alcohol aqueous solution is used for sequentially mixing, filtering and drying steel fibers and nano aluminum-silicon alloy powder, then a modified composite additive with polyvinyl alcohol attached to the surface is prepared, finally, a silane modified water reducing agent and aluminate cement are sequentially added into deionized water for mixing, and then the steel fibers and the nano aluminum-silicon alloy powder are uniformly mixed. Then the modified composite additive, the coarse aggregate, the fine aggregate, the fly ash and the mineral powder are sequentially added and mixed, and the concrete is prepared and has very excellent wear resistance and very good market application prospects.
本发明涉及一种超耐磨混凝土及其制备工艺，属于混凝土技术领域。本发明创造性地以带有双键的硅烷偶联剂作为改性剂，使其先水解缩聚再基于自由基聚合与甲基烯丙基聚氧乙烯醚、丙烯酸发生共聚，从而制得一种含有硅醇键的硅烷改性减水剂，接着利用聚乙烯醇水溶液对钢纤维和纳米铝硅合金粉末依次进行混合、过滤、干燥操作，进而制得一种表面附着有聚乙烯醇的改性复合助剂，最终，通过往去离子水中先依次加入硅烷改性减水剂和铝酸盐水泥进行混合，然后再依次加入改性复合助剂、粗骨料、细骨料、粉煤灰和矿粉进行混合，即制备出一种混凝土，拥有十分优异的耐磨性，市场应用前景非常好。
