External curing agent for concrete
The invention relates to the technical field of concrete admixtures, in particular to an external curing agent for concrete, which is prepared from 3-5 parts of styrene-acrylic emulsion, 0.3-0.5 part of water locking component, 0.03-0.05 part of reinforcing component, 0.04-0.08 part of system adjusting component and 85-95 parts of water, the styrene-acrylic emulsion, the water locking component, the reinforcing component and the water are mixed to obtain a mixed solution, and the mixed solution is mixed with the system adjusting component to obtain the external curing agent for the concrete. According to the concrete external curing agent, the water locking component has a large number of hydrophilic groups and a network structure with a certain degree of crosslinking, the water locking component and the styrene-acrylic emulsion can form a water locking protective film well, and therefore the concrete external curing agent has a good curing effect, and the reinforcing component is triethanolamine, so that the reinforcing effect is good. According to the present invention, the EM bacterial liquid is adopted as the system adjustment component, and the bacterial colony is adopted to degrade the curing film formed by the curing agent in the later period in the short time so as to effectively control the action time of the curing agent, such that the first-grade product requirement of the concrete external curing agent is achieved.
本发明涉及混凝土外加剂技术领域，具体为一种混凝土用外养护剂，包括苯丙乳液3‑5份、锁水组分0.3‑0.5份、增强组分0.03‑0.05份、体系调节组分0.04‑0.08份、水85‑95份，将所述苯丙乳液、锁水组分、增强组分和水混合得到混合液，再将所述体系调节组分与所述混合液混合即得到混凝土外养护剂，本发明通过锁水组分具有大量亲水基团与一定交联度的网络结构，可与苯丙乳液良好的形成锁水保护膜，从而对混凝土起到良好养护作用，通过增强组分为三乙醇胺，起到催化的作用，能够有效提高喷涂养护剂后混凝土的强度，通过采用EM菌液作为体系调节组分，通过菌落在后期短时间内降解养护剂形成的养护膜，有效控制养护剂作用时间，达到混凝土外养护剂一级品要求。
