different standards of cement have different quality and scope of application. In the face of a wide variety of home decoration cement products, it is difficult for ordinary consumers to accurately identify them: choosing cement is like feeling the pulse of traditional Chinese medicine. You should take it easy and step by step. The safest way is to choose products from regular manufacturers

step 1: “ Hope ” Mud knows its advantages and disadvantages. First, look at the packaging quality from the appearance. See whether the laminated woven bag with moisture-proof performance is not easy to be damaged, and whether the identification is clear and complete. Generally, the cement produced by regular manufacturers should be marked with the following contents: registered trademark, place of origin, production license number, executive standard, packaging date, net weight in bags, factory number, cement variety, etc. Poor quality cement is often vague about this

secondly, carefully observe the color of cement. Generally speaking, the normal color of cement should be gray white. If the color is too dark or changes, there may be too many other impurities

step 2: “ Smell ” Argillaceous quality. Smelling here is not smelling. After all, smelling cement is unsafe for consumers. Here's “ Smell ” Yes “ Listen ”, Listen to the merchants' introduction about the ingredients of cement, so as to infer the quality of cement. At present, in order to sell at a low price, some small cement factories in China violate the provisions of cement standards, use too much cement mixing materials, and do not mix raw materials in strict accordance with national standards, so the performance of their products can be imagined. While regular manufacturers are very strict in the selection of cement raw materials. The cement produced has the characteristics of moderate setting time, high bonding strength and good durability

step 3: “ Ask ” Source of mud. Mainly ask the cement manufacturer and production process to see its “ Origin ” Whether it is regular and whether the production process is advanced. At present, cement products in the building materials decoration market are mostly produced by small shaft kiln technology, which is not only very unstable in product quality, but also a great enemy of environmental protection; While some professional large factories adopt new dry rotary kiln production and advanced computer technology control management, which can ensure the stability of cement product quality

step 4: “ Cut ” Mud knows life. This step mainly uses fingers to give cement “ Pulse ”, Identify the length of delivery time. Cement also has a shelf life. Generally speaking, the strength of cement that exceeds the factory date by 30 days will decrease. The strength of cement stored for three months decreases by 10%-20%, 15%-30% after six months, and 25%-40% after one year. The cement that can be used normally should be free from moisture and caking. The high-quality cement twists the cement powder with fingers to feel the feeling of fine particles. The cement with poor packaging will be damp and caked during opening inspection; Poor quality cement twists the cement powder with fingers, which shows that the fineness of the cement is coarse and abnormal. When used, the strength is low and the viscosity is very poor
