Pervious concrete reinforcer based on artificial marble leftover materials as well as preparation method and application of pervious concrete reinforcer
The invention belongs to the field of preparation of pervious concrete enhancers, and relates to a pervious concrete enhancer based on artificial marble leftover materials and a preparation method and application thereof. The artificial marble leftover material is dried and ground into a coarse grinding material, then the coarse grinding material, a grinding aid, a dispersing agent and water are mixed and ball-milled, and the ball-milled material is dried to obtain a powdery finished product; mixing the powdery finished product with an acrylic acid solution for reaction, and drying to obtain powder; adding water into the powder for dispersing, and then adding an initiator, an accelerant and a cross-linking agent to prepare a calcium acrylate polymer solution; and compounding the calcium acrylate polymer solution with a polycarboxylate superplasticizer, nano-silica sol, nano-cellulose sol, silica fume and sodium nitrite to obtain the water reducing agent. The pervious concrete reinforcing agent based on the artificial marble leftover materials is used for preparing pervious concrete, the strength performance and the pervious performance of the pervious concrete can be synchronously improved, and meanwhile the contractility of the pervious concrete is improved.
本发明属于透水混凝土强化剂制备领域，涉及基于人造大理石边角料的透水混凝土强化剂及其制备方法与应用。将人造大理石边角料干燥粉磨为粗磨料，然后与助磨剂、分散剂和水混合球磨，将球磨料干燥，得粉状成品；将粉状成品和丙烯酸溶液混合反应，干燥得粉末；将粉末加水分散，然后加入引发剂、促进剂和交联剂，配制得到丙烯酸钙聚合物溶液；将所述丙烯酸钙聚合物溶液与聚羧酸高效减水剂、纳米二氧化硅溶胶、纳米纤维素溶胶、硅灰、亚硝酸钠进行复配，即得。本发明提供的基于人造大理石边角料的透水混凝土强化剂用于制备透水混凝土，能够实现透水混凝土强度性能和透水性能的同步改进，同时透水混凝土的收缩性改善。
