High-bending-resistance cement-based material and preparation method thereof
The invention discloses a high-bending-resistance cement-based material and a preparation method thereof, and relates to the technical field of concrete. The high-bending-resistance cement-based material comprises a cement hydrate and a high-molecular polymer chemically bonded with the cement hydrate, wherein the high-molecular polymer is obtained by in-situ polymerization of a polymerization monomer in cement under the action of an initiator and an accelerator. According to the preparation method of the high-flexural-strength cement-based material, the polymerization monomer, the initiator and the accelerator are mixed and dissolved and then subjected to in-situ polymerization in cement, the formed high-molecular polymer and cement hydrate are connected in a chemical bonding mode, and theflexural strength of the cement-based material is effectively improved.
本发明公开了高抗折水泥基材料及其制备方法，涉及混凝土技术领域。高抗折水泥基材料包括水泥水化物和与水泥水化物化学键合的高分子聚合物，高分子聚合物是由聚合单体在引发剂和加速剂的作用下在水泥中原位聚合而得。高抗折水泥基材料的制备方法通过将聚合单体、引发剂和加速剂混合溶解后在水泥中进行原位聚合，形成的高分子聚合物和水泥水化物通过化学键合的方式连接，有效提升了水泥基材料的抗折强度。
