Description

technical field

[0001] The invention relates to a kind of cement, in particular to a kind of decorative cement, which belongs to the technical field of building materials. Background technique

[0002] Industrial buildings are mostly concrete structures, steel-concrete structures, steel structures, etc., and their exterior wall materials may be steel plates, wood panels, or calcium-silicon panels. The environment is also more in line with the aesthetic style of modern people, which is confirmed by more and more fair-faced concrete construction industries. Existing decorative cements include white cement and colored cement, which are mainly used in construction projects. It can be formulated into colored mortar or made into various colored and white concrete. Compared with natural decorative materials, it has the advantages of convenient use, easy color adjustment and low price, but its adhesion is poor, and it is easy to fall off the surface of steel plates, wood boards, e...
