The second: "smell" Analysis of the quality of mud here, "smell" is not smell the smell, the smell after the cement is unsafe for consumers, where the "news" is "listening" white cement, listen to business reports on cement batching, so as to infer the quality of the cement. Some small domestic cement For low-cost sales of cement density, in violation of cement standards, excessive use of cement mixed material is not in strict accordance with national standards for raw material ratio, its performance can be imagined. The regular cement manufacturers in the choice of raw materials is very strict on to produce cement with a moderate setting time, high bond strength, durability and good. The fourth: "Cut" mud-known life of this step to cement mainly used fingers to "pulse", to identify their length of time in the factory. Cement also has shelf life, generally cement pipe machine, more than 30 days of the date of manufacture of cement strength will decline. Cement its strength after storage for three months decreased by 10% to 20% of cement, after a year reduced by 25% -40%. Proper use of cement should be no damp agglomeration, high-quality cement with a finger twist cement powder, feel the feeling of fine particles. Packaging inferior cement, opening inspection will damp and agglomeration; inferior cement cement powder with your fingers twist, a rough sense, indicating that the cement fineness thick, is not normal, when the use of low-intensity, viscosity is poor. _ _ Caidian cement mortar cement provided by Wuhan Hongshan District of Wuhan pavilion cement operation.
