What is the price of cement? Introduction to shopping purposes

Among many building materials, cement is the most widely used, and the high-rise buildings and building materials people see are mainly cement. Cement needs to be mixed with water to be firm, and it should be implemented in strict proportion. Cement is much cheaper than other building materials, but it is used much more, so its price is also concerned. There are countless buildings made of cement, and people will naturally worry about their quality. Here, we will introduce the price of cement and its purchase.

Types of cement

1, white portland cement: calcium silicate is the main component, and a small amount of iron clinker and appropriate amount of gypsum are added for grinding.

2. Colored Portland cement: white Portland cement clinker and high-quality white gypsum are mixed with pigments and additives and ground. Commonly used color pigments include iron oxide (red, yellow, brown and black), manganese dioxide (brown and black), chromium oxide (green), cobalt blue (blue), ultramarine (indigo), Kong Quelan (navy blue) and carbon black (black). Decorative cement is similar to portland cement, with the same construction and maintenance, but it is easy to be polluted, and the instruments and tools must be clean.

Application and procurement of cement

In home decoration, cement mortar is used for sticking and masonry of floor tiles and wall tiles, which can not only enhance the adsorption capacity of surface materials and grass-roots units, but also protect the internal structure, and can be used as a leveling layer for rough surfaces of buildings, so cement mortar is an essential material in decoration engineering.

Many customers think that the greater the proportion of cement in the whole mortar, the stronger its cohesiveness, so they often disagree with the decoration company on the amount of cement. In fact, if the cement label is too large, when the cement mortar sets, the cement will absorb a lot of water. At this time, the tiles on the surface layer absorb too much water and are easy to crack, shortening the service life. Generally, cement mortar should be mixed according to the ratio of cement: sand = 1: 2 (volume ratio).

There are many kinds of cement in the market, including portland cement, ordinary portland cement, composite portland cement and slag portland cement. Ordinary portland cement or composite portland cement is commonly used in home decoration.

Only when you can buy cement can you choose high-quality products, and people will feel at ease when using them. The firmness of the house is actually very important. Usually everyone doesn't care much, but once a disaster happens, it will be reflected. Some houses collapsed in the earthquake, largely because of their poor workmanship. In addition to cement, cheap cement can be used, but it cannot guarantee the firmness of the finished products. The quality of cement comes first, so don't care too much about the high price.
