Anti-crack concrete and preparation method thereof
The invention discloses anti-crack concrete and a preparation method thereof, and relates to the field of concrete.The anti-crack concrete is prepared from, by weight, 120-180 parts of modified fine aggregate; 200 to 300 parts of coarse aggregate; 120 to 160 parts of cement; 30 to 50 parts of water; 4-8 parts of a water reducing agent; 1-2 parts of a modified fiber net; 2.5 to 3.5 parts of a retarder; a preparation method of the modified fiber net comprises the following steps: soaking polypropylene net-shaped fibers in a polyacrylamide solution, and drying to obtain the modified fiber net. The concrete has the effect of improving the compressive strength and crack resistance of the concrete.
本申请公开了一种抗裂混凝土及其制备方法，涉及混凝土领域，其由包括以下重量份的组分制备得到：改性细骨料120‑180份；粗骨料200‑300份；水泥120‑160份；水30‑50份；减水剂4‑8份；改性纤维网1‑2份；缓凝剂2.5‑3.5份；所述改性纤维网的制备方法如下：将聚丙烯网状纤维在聚丙烯酰胺溶液中浸泡、干燥，得到改性纤维网。本申请具有提高混凝土的抗压强度和抗裂能力的效果。
