Preparation method of anti-cracking concrete
The invention relates to the technical field of concrete preparation, in particular to an anti-cracking concrete preparation method which comprises the following steps: S1, taking cement, fly ash, gravel, hybrid fiber, an additive, river sand, water-absorbent resin and water according to a stoichiometric ratio; s2, pouring the cement, the fly ash and the gravel river sand into a stirring tank, pouring water into the stirring tank, and fully stirring and mixing to obtain a mixture A; s3, hybrid fibers are poured into the mixture A, water is poured into the stirring tank again, meanwhile, water-absorbent resin is added, secondary stirring is conducted, full mixing is conducted, and a mixture B is obtained; s4, an additive is poured into the mixture, the remaining 1/3 of water is poured into the stirring tank, stirring is conducted for the third time, full mixing is conducted, and concrete slurry is obtained; s5, the concrete slurry is subjected to pouring treatment in sequence, anti-cracking concrete is prepared, in the concrete preparation process, an alkaline additive is added, the concrete can keep good compressive strength and breaking strength, and the crack resistance of the concrete can also be improved.
本发明涉及混凝土制备技术领域，尤其涉及一种抗开裂的混凝土制备方法，包括如下步骤：S1、按计量比移取水泥、粉煤灰、碎石、混杂纤维、添加剂、河砂、吸水树脂和水；S2、将水泥、粉煤灰、碎石河砂倒入搅拌罐中，向搅拌罐中倒入水，充分搅拌混合，得混合物A；S3、向混合物A中倒入混杂纤维，再次向搅拌罐中倒入水，同时添加吸水树脂，二次搅拌，充分混合，得混合物B；S4、向混合物中倒入添加剂，并将剩余1/3的水量倒入搅拌罐，三次搅拌，充分混合，得混凝土浆料；S5、将混凝土浆料依序进行浇筑处理，制得抗开裂混凝土，在混凝土制备的过程中，添加碱性添加剂，不仅能够使混凝土保持良好的抗压强度和抗折强度，还能够提高混凝土的抗裂性。
