Green anti-cracking premixed concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses green anti-cracking premixed concrete and a preparation method thereof. The green anti-cracking premixed concrete is prepared from the following raw materials in parts by weight: Portland cement, superfine fly ash, slag powder, river sand, broken stone, a polycarboxylic acid superplasticizer, waste concrete aggregate, ammonium polyphosphate modified wheat straw fibers, self-repairing microcapsules and water. The preparation method of the green anti-cracking premixed concrete comprises the following steps: S1, mixing and stirring the ammonium polyphosphate modified wheat straw fibers, the water and the self-repairing microcapsules to obtain a mixture A; s2, adding Portland cement, superfine fly ash, river sand, gravel, a polycarboxylic acid superplasticizer, waste concrete aggregate and slag powder into the mixture A, and stirring to obtain the green anti-cracking premixed concrete. The prepared green anti-cracking premixed concrete is excellent in anti-cracking performance, non-renewable mine resources are utilized, and the green anti-cracking premixed concrete is green and environmentally friendly.
本申请涉及混凝土技术领域，具体公开了一种绿色抗裂预拌混凝土及其制备方法。一种绿色抗裂预拌混凝土，包括如下重量份原料：硅酸盐水泥、超细粉煤灰、矿渣粉、河砂、碎石、聚羧酸高效减水剂、废旧混凝土集料、聚磷酸铵改性麦秸纤维、自修复微胶囊和水。一种绿色抗裂预拌混凝土的制备方法，包括以下步骤：S1、将聚磷酸铵改性麦秸纤维、水和自修复微胶囊混合搅拌，得到混合物A；S2、向混合物A中加入硅酸盐水泥、超细粉煤灰、河砂、碎石、聚羧酸高效减水剂、废旧混凝土集料、矿渣粉后，搅拌，制得所述绿色抗裂预拌混凝土。本申请制得的绿色抗裂预拌混凝土的抗裂性能优异，利用了不可再生的矿山资源，绿色环保。
