Concrete reinforcing and toughening admixture and preparation method thereof
The invention relates to the technical field of concrete additives, in particular to a concrete reinforcing and toughening additive and a preparation method thereof. The concrete reinforcing and toughening admixture is prepared from the following preparation raw materials: an unsaturated polyoxyethylene ether monomer, an esterification monomer, a quaternary ammonium salt cationic monomer, methacrylic acid, a graphene oxide solution, a reducing agent, a chain transfer agent and an oxidizing agent. The concrete reinforcing and toughening admixture provided by the invention has good dispersity and structural adjustability, can promote a cement hydration product in set cement to form a regular microstructure, realizes hydration orderliness, and has a significant improvement effect on the working performance and durability of concrete.
本发明涉及混凝土添加剂技术领域，特别涉及一种混凝土增强增韧外加剂及其制备方法，其中，所述混凝土增强增韧外加剂包括以下制备原料：不饱和聚氧乙烯醚单体、酯化单体、季铵盐阳离子单体、甲基丙烯酸、氧化石墨烯溶液、还原剂、链转移剂、氧化剂。本发明提供的混凝土增强增韧外加剂具有良好的分散性和结构可调性，且能促进水泥石中水泥水化产物形成整齐规整的微观结构，实现水化的有序性，对混凝土工作性能和耐久性能有着显著提高效果。
