Polypropylene fiber modified rubber concrete and preparation method thereof
The invention discloses a polypropylene fiber modified rubber concrete and a preparation method thereof. The polypropylene fiber modified rubber concrete is prepared from the following components in parts by weight: 488 parts of cement, 168 parts of water, 663-746 parts of sand, 973 parts of broken stone, 7.3 parts of a water reducing agent, 32.2-64.4 parts of rubber particles, and 1 part of polypropylene fibers, wherein the modified rubber particles replace part of sand according to the equal volume of 10%-20%. The preparation method of the polypropylene fiber modified rubber concrete comprises the following steps: preparing the raw materials according to the mass fraction; starting a stirrer, sequentially adding the weighed broken stone, polypropylene fibers, sand and modified rubber particles into the stirrer, stirring for 30 seconds to uniformly mix the aggregate, adding cement, and stirring for 10 seconds; dissolving a poly-carboxylic acid high-performance water reducing agent into water according to a weight ratio, uniformly stirring to form a water reducing agent solution, adding the water reducing agent solution into the stirrer, and stirring for 2 minutes to obtain the polypropylene fiber modified rubber concrete.
本发明公开了一种聚丙烯纤维改性橡胶混凝土及其制备方法，包括水泥、水、砂、碎石、减水剂和聚丙烯纤维，其中，改性橡胶颗粒按10％—20％等体积取代部分砂，由如下质量分数的各原料组成：水泥488份，水168份，砂663—746份，碎石973份，减水剂7.3份，橡胶颗粒32.2—64.4份，聚丙烯纤维1份。所述聚丙烯纤维改性橡胶混凝土的制备方法为：按照质量分数准备各原料；开动搅拌机，将称量好的碎石、聚丙烯纤维、砂和改性橡胶颗粒依次投入搅拌机内，搅拌30s使集料混合均匀，再投入水泥搅拌10s；将聚羧酸高性能减水剂按重量比例溶于水，搅拌均匀形成减水剂溶液，将所述减水剂溶液加入搅拌机中，搅拌2min得到聚丙烯纤维改性橡胶混凝土。
