Identification of Cement Quality first: "Hope" mud know the pros and cons first appearance package quality. To see if the use of the moisture-proof performance is good unbreakable Fumo bags, see the sign is clear and complete. Typically, regular factory produced cement shall be marked with the following: registered trademark, origin, production license number, performance standards, packaging date, net bags, serial number, and other varieties of cement. The poor quality of cement is often vague on this. Secondly, careful observation of the color of cement. In general, the normal color was gray cement should Wuhan cement, dark or there is a change there may be too many other impurities. Quick-setting cement means a cement premature curing abnormal or premature hardening phenomenon. The heat causes the gypsum crystal water dehydration Wuhan cement brick machine, into a slurry body, and thus lose the ability to regulate the setting time. False set phenomenon related to many factors, generally believed to be primarily due to the cement grinding mill when the temperature is higher, so that dehydration of gypsum hemihydrate gypsum sake. When mixed with water, cement, hemihydrate rapidly react with water to gypsum cement, needle-like crystals formed network structure Wuhan Portland cement, resulting slurry is cured. In addition, some high alkali cement, potassium sulfate, potassium and gypsum plaster grow rapidly generate, also cause false set. False set and fast-setting different from the former little heat release, and by vigorously stirring the slurry recoverable plastic and achieve normal coagulation, without adversely affecting the strength. _ Wuhan Wuhan cement prices Cement (certified) _ East Lake Cement provided by Hongshan District of Wuhan pavilion cement operation.
