High-strength impervious concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength impervious concrete and a preparation method thereof, and the high-strength impervious concrete comprises the following raw materials: cement, machine-made sand, gravel, a high-strength admixture, an early-strength polycarboxylic acid high-performance water reducing agent, an anti-corrosion and anti-rust agent and water. The highest compressive strength of the concrete is 105 MPa, the lowest slump is 22 mm, the compressive strength and breaking strength of the concrete are improved, and the slump of the concrete is reduced. Besides, the concrete is found to have the lowest water mark height of 9mm through anti-permeability performance detection, the anti-permeability grade can reach P20, and the concrete has high anti-permeability.
本申请涉及混凝土技术领域，具体公开了一种高强抗渗混凝土及其制备方法，其包括如下原料：水泥，机制砂、碎石、高强掺合料、早强型聚羧酸高性能减水剂、防腐防锈剂和水。本申请得到的混凝土抗压强度最高为105MPa，且坍落度最低为22mm，提高了混凝土的抗压强度和抗折强度，并降低了混凝土坍落度。另外，混凝土通过抗渗性能检测发现，水痕高度最低为9mm，抗渗等级可达到P20，具有较高的抗渗性。
