Abstract

The invention discloses environment-friendly decoration cement and belongs to the technical field of building materials. The environment-friendly decoration cement is prepared from the following raw materials in parts by weight: 45-60 parts of Portland cement, 0-4 parts of an expanding agent, 4-10 parts of metakaolin, 2-6 parts of silicon powder, 1-3 parts of crystal whiskers, 5-10 parts of redispersible emulsion powder, 1-2 parts of a water reducer, 0.3-1.0 part of a defoaming agent, 0.1-0.15 part of cellulose ether, 5-10 parts of ground calcium carbonate and 10-15 parts of an environment-friendly material. The environment-friendly decoration cement disclosed by the invention has no problems such as alkali efflorescence and cracking and has good peaceability, corrosion resistance and environment-friendly performance.

Description

technical field [0001] The invention relates to cement, in particular to an environment-friendly 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 board...
