Inorganic concrete sealing curing agent and preparation method and application thereof
The invention provides an inorganic concrete sealing curing agent as well as a preparation method and an application thereof, and belongs to the technical field of concrete curing for sealing and curing to achieve spraying type saturated water curing. In the inorganic concrete sealing curing agent provided by the invention, the mass concentration of sodium oxide is 4-12%, the mass concentration ofsilicon dioxide is 22.5%-35.2%, the mass concentration of the reinforcing agent is 6.5%-16%, the mass concentration of the permeation curing agent is 4-9%, the mass concentration of the shrinkage reducing agent is 2.5-10%, the mass concentration of the coagulant is 1.5-4.5%, and the balance is water. The inorganic concrete sealing curing agent provided by the invention can effectively improve thestrength of concrete, and after the inorganic concrete sealing curing agent is sprayed on the surface of the concrete, a formed film can enable the surface of the concrete to be in a water-saturatedclosed state within 14 days and can be automatically degraded and absorbed within 28 days, so that the sealing degree of the surface of the concrete is greater than 98%, and the strength is improved by 3-10 MPa; the inorganic concrete sealing curing agent has the characteristics of low cost, convenience in construction, no white pollution and excellent curing effect, and can truly realize naturalsaturated water curing.
本发明提出无机混凝土密封养护剂及其制备方法和应用，属于混凝土养护技术领域进行密封固化，达到喷涂式饱水养护。本发明提供的无机混凝土密封养护剂中氧化钠的质量浓度为4‑12％、二氧化硅的质量浓度为22.5％‑35.2％、增强剂的质量浓度为6.5％‑16％、渗透固化剂的质量浓度为4‑9％、减缩剂的质量浓度为2.5‑10％、混凝剂的质量浓度为1.5‑4.5％，余量为水。本发明提供的无机混凝土密封养护剂可有效增加混凝土强度，在混凝土表面喷涂后，所形成的薄膜在14d内可将混凝土表面处于饱水封闭状态下，并且在28d可实现自动降解、吸收，使得混凝土表面的封闭度＞98％，强度提高3‑10兆帕，该无机混凝土密封养护剂具有成本低、施工方便，不产生白色污染，养护效果极佳的特点，可真正实现自然饱水养护。
