Method for preparing high-strength concrete
The invention discloses a method for preparing high-strength concrete, and relates to the technical field of concrete preparation, the preparation method comprises the following operation steps: S1, weighing ethyl acetate, adding into a reaction kettle, adding physcion, and then adding zeolite; s2, plant fibers and sepiolite are put into a pulverizer to be pulverized and then screened through a 100-mesh sieve, and mixed powder is obtained; s3, adding the cement, the quartz powder and the sand into a stirrer for stirring; s4, adding steel fibers into the dry mixture, continuously stirring in a stirrer, then adding water and gravel, and stirring for 4-10 minutes; and S5, adding the hydrophobic agent and the polyamide curing agent into the stirrer, and continuously stirring to obtain the high-strength concrete. According to the high-strength concrete produced by the method for preparing the high-strength concrete, cracks in the concrete can be avoided under the condition of rapid drying, the ductility of the high-strength concrete is enhanced by adding the steel fibers, and the high-strength concrete is not easy to break.
本发明公开了一种用于制备高强度混凝土的方法，涉及混凝土制备技术领域，所述制备方法包括下述操作步骤：S1、称乙酸乙酯加入到反应釜中，加入大黄素甲醚，然后加入沸石；S2、将植物纤维和海泡石投入粉碎机中进行粉碎，然后经过100目的筛子进行筛选得到混合粉末；S3、将水泥、石英粉和沙子加入到搅拌机中进行搅拌；S4、向干混料中加入钢纤维在搅拌机中持续进行搅拌，然后加入水和碎石搅拌4‑10分钟；S5、向搅拌机中加入疏水剂和聚酰胺固化剂持续搅拌制得高强度混凝土。该用于制备高强度混凝土的方法，生产出来的高强度混凝土能够避免在快速干燥的情况下避免混凝土的内部出现裂缝，添加了钢纤维增强了该高强度混凝土的延展性、不易断裂。
