Method for improving durability of concrete product by using carbonized coating
The invention discloses a method for improving durability of a concrete product by using a carbonized coating, which comprises the following steps: uniformly mixing 80-100 parts of a carbonized active cementing material, 0-20 parts of an auxiliary calcium source, 0.1-2.0 parts of a carbonized layer reinforcing agent, 1-6 parts of a water reducing agent and 25-45 parts of water to obtain a carbonized coating; and coating the carbonized coating on the surface of a product matrix, and standing and carbonizing to obtain the concrete product coated with the carbonized coating. By introducing the auxiliary calcium source, the carbonization time can be shortened, the utilization rate and the production efficiency of the carbonization device can be improved, and the requirements of a product production process are met; and by applying the carbonized coating prepared from the carbonized active cementing material such as the steel slag to the surface of the concrete product, the purpose of economically, conveniently and effectively improving the durability of the concrete product through the calcium carbonate coating is achieved, meanwhile, the application range of the carbonized active cementing material is widened, a large amount of carbon dioxide can be immobilized, and the method has obvious environmental benefits.
本发明公开一种利用碳化涂层提高混凝土制品耐久性的方法，包括以下步骤：将80‑100份碳化活性胶凝材料、0‑20份辅助钙源、0.1‑2.0份碳化层增强剂、1‑6份减水剂和25‑45份水混合均匀，得到碳化涂料；将碳化涂料涂覆在制品基体表面，经静置和碳化后得到涂覆有碳化涂层的混凝土制品。本发明通过引入辅助钙源，能够缩短碳化时间，有利于提高碳化装置利用率和生产效率，满足制品生产工艺需求；本发明通过将钢渣等碳化活性胶凝材料制备的碳化涂层应用到混凝土制品表面，实现了通过碳酸钙涂层经济、方便、有效地提高混凝土制品耐久性能的目的，同时拓宽了碳化活性胶凝材料的应用范围，且能大量固存二氧化碳，具有显著的环境效益。
