The invention discloses sound absorption and noise reduction concrete, and relates to the technical field of building materials. When the sound-absorbing and noise-reducing concrete is prepared, the modified polypropylene fiber is added into the cement, the modified polypropylene fiber is prepared by grafting a polycarboxylic acid water reducing agent blank on polypropylene fine fiber subjected to plasma treatment and then grafting methanesulfonyl chloride substituted polyethylene glycol monomethyl ether on the polycarboxylic acid water reducing agent blank, and the modified polypropylene fiber is prepared by adding the modified polypropylene fiber into the cement. Finally, plasma treatment is carried out, and the polycarboxylate superplasticizer blank is prepared through copolymerization of acrylic acid, polyethylene glycol methyl methacrylate and sodium allysulfonate; the prepared sound-absorbing and noise-reducing concrete has sound-absorbing and noise-reducing performance, and is relatively good in dispersity and flowability, and relatively high in toughness and crack resistance in the later hardening period.
本发明公开了一种吸声降噪混凝土，涉及建筑材料技术领域。本发明制备在吸声降噪混凝土时，将改性聚丙烯纤维加入水泥中制得，改性聚丙烯纤维是在经过等离子体处理的聚丙烯细纤维上接枝聚羧酸减水剂坯料，再在聚羧酸减水剂坯料上接枝甲磺酰氯取代的聚乙二醇单甲醚，最后再进行等离子体处理制得，聚羧酸减水剂坯料是用丙烯酸、聚乙二醇甲基丙烯酸甲酯和烯丙基磺酸钠进行共聚制得；本发明制备的吸声降噪混凝土，在具备吸声降噪性能的同时，分散性和流动性较好，硬化后期的韧性和抗裂性较高。
