Moisture phenomenon 1: Cement products are aggregated into small particles, but they are turned into powder by pinching with hands, and there are no loose particles.
Analysis and treatment: This shows that the cement products have begun to get wet, but the situation is not too severe, and the strength loss is not large. It is claimed that we can find a way to compact cement products into powders or add mixing moments to determine the strength of cement from scratch. Jilin Cement Pipe Factory has suggested that if cement strength testing is not carried out, it can only be used in locations where the strength requirement is 15 to 20% lower than originally intended.
Moisture phenomenon 2: Cement products have been partially hardened; the outside is hard and fast, and there is still powder inside.
Analysis and treatment: This shows that the moisture of cement products is very severe, and the strength loss has reached more than half. Jilin Cement Pipe Factory advocates using a sieve to remove hard pieces, and those that can be crushed into powder are crushed to determine the strength of cement products from scratch. Jilin Cement Pipe Factory advises that if the strength of the cement is not measured, it can only be used in areas with little force. Generally, it can only be used in places where the wear resistance such as wall plastering is low.
Moisture phenomenon 3: Cement products form large lumps, no powder is visible.
