Mud-resistant concrete water reducing agent and preparation method thereof
The invention relates to the technical field of concrete, and discloses an anti-mud type concrete water reducing agent and a preparation method thereof.The preparation method comprises the steps that a polycarboxylic acid water reducing agent, quaternized siloxane and bentonite are added into a stirrer to be stirred, and the anti-mud type concrete water reducing agent is obtained after stirring is finished; carbon nano tubes contained in quaternized siloxane can physically or chemically interact with a cement-based material, the mechanical property of the concrete is enhanced through the nano effect, gaps in the concrete can be filled with silane contained in the quaternized siloxane, and therefore the compactness of the concrete is improved, and the service life of the concrete is prolonged. The breaking strength of the concrete and the mud resistance of the concrete are also obviously improved; the quaternary ammonium salt improves the fluidity of the concrete, inhibits slump loss and improves the strength of the concrete.
本发明涉及混凝土技术领域，且公开了一种抗泥型混凝土减水剂及其制备方法，本发明通过将聚羧酸减水剂、季铵化硅氧烷、膨润土加入到搅拌器中，搅拌，结束后得到抗泥型混凝土减水剂；季铵化硅氧烷中含有的碳纳米管可以和水泥基材料发生物理或化学相互作用，并通过纳米效应，增强混凝土的力学性能，其中含有的硅烷可以填充到混凝土中的空隙中，从而提高混凝土的密实性，也显著提高混凝土的抗折强度和提高混凝土的抗泥性；季铵盐提高混凝土的流动性、抑制坍落度损失、提高混凝土强度。
