External curing agent for concrete
The invention discloses an external curing agent for concrete. The external curing agent for concrete is prepared from the following raw materials: a modified polyolefin wax emulsion, an organic emulsion, a silane coupling agent, a reinforcing agent and an inorganic densifying component. According to the concrete external curing agent, the modified polyolefin wax emulsion is adopted as a main rawmaterial and contains part of the reinforcing agent; water retention is conducted through the film forming effect of the wax emulsion and the organic emulsion, meanwhile, the reinforcing agent is added to serve as a catalyst, and hydration of the tricalcium aluminate content in concrete and formation of ettringite are accelerated, and a certain reinforcing effect is achieved. According to the concrete external curing agent, the curing cost of concrete is greatly saved, the water retention rate and the compressive strength are greatly improved, and secondary pollution to the surface of the concrete is avoided.
本发明公开了一种混凝土外养护剂，该混凝土外养护剂的原料包括改性聚烯烃蜡乳液、有机乳液、硅烷偶联剂、增强剂及无机增密组分。本发明制备的混凝土外养护剂，采用了改性聚烯烃蜡乳液为主要原料且含有部分增强剂，通过蜡乳液和有机乳液的成膜作用进行保水的同时，还通过加入增强剂作为催化剂，加速混凝土中的铝酸三钙含量的水化和钙矾石的形成而起到一定的增强作用。本发明的混凝土外养护剂，大幅度节约了混凝土的养护成本，大大提高了保水率和抗压强度且不会对混凝土表面造成二次污染。
