Quick-setting cement means a cement premature curing abnormal or premature hardening phenomenon. The heat causes dehydration of gypsum in crystalline water 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 high temperature in the cement grinding mill, cement spikes offer, so dehydration of gypsum hemihydrate gypsum sake. When mixed with water, cement, hemihydrate rapidly gypsum reacts with water to form needle-like crystal network structure, resulting slurry is cured. In addition, some high alkali cement, potassium sulfate, potassium and gypsum plaster grow rapidly generate spikes cement, can 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. Portland cement: from Portland cement clinker, 6% to 20% of the mixed material, the amount of gypsum ground made of cement matrix, called Portland cement (referred to ordinary cement), Code: PO. Slag cement: cement matrix by the Portland cement clinker, 20% to 70% and the amount of granulated blast furnace slag grinding made of plaster, called slag cement, code: PS.
