Abstract

The invention discloses a radiation-proof decoration cement, and belongs to the technical field of building materials. The decoration cement comprises, by weight, 40-50 parts of radiation-proof cement, 0-4 parts of an expanding agent, 4-10 parts of metakaolin, 2-6 parts of silicon powder, 1-3 parts of whiskers, 5-10 parts of redispersible latex powder, 1-2 parts of a water reducer, 0.3-1.0 part ofan antifoaming agent, 0.1-0.15 part of cellulose ether and 25-30 parts of barite powder. The radiation-proof cement is one of barium cement, strontium cement and boron-containing cement. The radiation-proof decoration cement has the advantages of no alkali efflorescence or cracking problems, good workability, good corrosion resistance and very strong radiation resistance.

Description

technical field [0001] The invention relates to cement, in particular to a radiation-proof 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, etc...
