Take a look to see if the cement paper bag packaging is intact and the labeling is complete. The markings on the paper bag include: factory name, production license number, cement name, registered trademark, variety (including variety code), label, packaging year, month, day and serial number.

Twist the cement powder with your fingers for a second time. If you feel it has a slightly fine, sandy, and powdery feel, it indicates that the cement fineness is normal.

Thirdly, look at the color. Observe whether the color is dark gray or dark green. Comparison of cement strength if the color is yellow or white (yellow indicates that the clinker is raw material, white indicates that the slag content is too much) Low.

Look at the time to see clearly the production date of the cement. The performance of cement that has exceeded its validity period of 30 days has declined. The strength of cement dropped by 10-20 after three months of storage, by 15-30 after six months, and by 25-40 after one year. High-quality cement can solidify in more than 6 hours. Cement that cannot set for more than 12 hours is of poor quality.
