Inspection production date
Usually the date of production is posted on the side or back of cement. Because cement is easy to get wet or agglomerate after being left for a long time, it usually takes two weeks at most from the factory to the purchase, and the implementation standard should be GB 175-2007.
Look at the color of cement.
Usually, the normal color of cement is grayish white. If you find that the color of the cement you bought is too dark or has changed, it is likely that there are too many other impurities. In addition, according to national regulations, the name and strength grade of cement should be printed on both sides of the packaging bag according to the purpose of cement.
Look at the packaging
The quality of cement can also be seen through the packaging of cement. For example, whether the package is intact and the label is clear. Usually, the labels on paper bags include factory name, production license number, name, registered trademark, production date and number, etc.
