防护工程的加固改造和快速抢修对混凝土材料的早期抗压强度和粘结强度要求较高。为此,在普通混凝土配合比的基础上,掺加不同掺量丙烯酸酯共聚乳液(NYS)聚合物,通过调整水灰比,得到早期抗压强度高的NYS聚合物混凝土的配合比;采用锲形劈裂拉伸试验装置,对NYS聚合物混凝土与普通混凝土进行粘结性能试验,得到NYS聚合物混凝土粘结强度。结果表明:NYS聚合物混凝土早期抗压强度和粘结强度均高于普通混凝土,NYS聚合物混凝土可以用于防护工程的快速加固和抢修。 Reinforcement of the protection of the project and rapid repair of concrete early compressive strength and bond strength requirements. Therefore, based on the mix proportion of ordinary concrete, the blending ratio of NYS polymer concrete with high initial compressive strength was obtained by adding different content of acrylamide copolymer emulsion (NYS) polymer by adjusting the ratio of water to cement. Shape splitting tensile test device, the NYS polymer concrete and ordinary concrete bonding performance test to get NYS polymer concrete bond strength. The results show that the early compressive strength and the bond strength of NYS polymer concrete are higher than ordinary concrete, NYS polymer concrete can be used for rapid reinforcement and repair of protective engineering.
