Anti-crack recycled concrete as well as preparation method and application thereof
The invention relates to the technical field of concrete, and particularly discloses anti-crack recycled concrete as well as a preparation method and application thereof. The anti-crack recycled concrete is prepared from the following raw materials: cement, water, a water reducing agent, fine aggregate, coarse aggregate, a filler, graphene modified basalt fibers and polystyrene microspheres, wherein the fine aggregate comprises sand and recycled fine aggregate; and the coarse aggregate comprises fine stone and recycled coarse aggregate. A preparation process of the graphene modified basalt fibers comprises the following steps: mixing basalt fibers, graphene, liquid paraffin and a silane coupling agent, performing melt extrusion and granulation, and then performing cooling, blow-drying and pelletizing to obtain the graphene modified basalt fibers. The particle sizes of the polystyrene microspheres are in a range of 180-220 nm. The anti-crack recycled concrete disclosed by the invention has relatively good anti-crack and anti-compression properties.
本申请涉及混凝土技术领域，具体公开了一种抗裂再生混凝土、其制备方法及应用。抗裂再生混凝土制备所用原料由如下组分组成：水泥、水、减水剂、细骨料、粗骨料、填料、石墨烯改性玄武岩纤维、聚苯乙烯微球；细骨料包括砂子和再生细骨料；粗骨料包括细石和再生粗骨料；石墨烯改性玄武岩纤维的制备过程为：将玄武岩纤维、石墨烯、液体石蜡、硅烷偶联剂混合后，熔融挤出，造粒，后通过冷却、吹干、切粒，即得石墨烯改性玄武岩纤维；聚苯乙烯微球的粒径为180‑220nm。本申请的抗裂再生混凝土具有较好的抗裂抗压性能。
