Decorative cement variety Decorative cement is often used to decorate the surface of buildings. It is simple in construction, convenient in shape, easy to maintain, and inexpensive. The varieties are as follows: (1) White Portland cement: It is made of calcium silicate as the main component, a small amount of iron clinker and a proper amount of gypsum. (2) Color Portland cement: It is made of white Portland cement clinker and high-quality white gypsum, mixed with pigment and admixture. Commonly used color additive pigments are iron oxide (red, yellow, brown, black), manganese dioxide (brown, black), chromium oxide (green), cobalt blue (blue), ultramarine blue (indigo), peacock blue (sea blue) ), carbon black (black), etc. Color Portland cement decorative cement is similar to Portland cement, with the same construction and maintenance, but it is relatively easy to pollute, and the instrument tools must be clean. Application and purchase In the home decoration, cement mortar should be used for floor tiles, wall tiles and masonry. It can not only enhance the adsorption capacity of the surface material and the base layer, but also protect the internal structure and serve as a leveling layer for the construction of the rough surface. Therefore, cement mortar is an indispensable material in the renovation project. Many customers believe that the greater the proportion of cement in the entire mortar, the stronger its adhesion, so it often differs from the decoration company in the amount of cement used. In fact, in the case of pasted tiles, if the cement label is too large, when the cement mortar is condensed, the cement absorbs a large amount of water. At this time, the moisture of the tile of the surface layer is excessively absorbed, which is easy to crack and shorten the service life. Cement mortar should generally be stirred in the proportion of cement: sand = 1:2 (volume ratio). At present, there are many varieties of cement on the market, such as Portland cement, ordinary Portland cement, composite Portland cement, slag Portland cement, etc., ordinary Portland cement or composite Portland cement is commonly used in home decoration. .
