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 cement board, are 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 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, also cause false set. False set and fast-setting different from the former little heat release, and by vigorously stirring the slurry recoverable plastic cement tile, and achieve normal coagulation, without adversely affecting the strength. Decorative cement commonly used in the decoration of the building surface, the construction is simple, easy modeling, easy maintenance Jiangxia cement, cheap. There are several varieties: (1) white Portland cement: calcium silicate as the main ingredient, add a small amount of iron Portland cement clinker and the amount of color from finely ground gypsum. (2) Color portland cement: the white Portland cement and clinker quality white plaster, mixed with pigments, additives common ground together. Common color mixing iron oxide pigment (red, yellow, brown, black) density cement, manganese dioxide (brown, black), chromium oxide (green), cobalt blue (blue), ultramarine blue (indigo), peacock blue (navy), carbon black (black) and the like. Decorative cement and Portland cement is similar to the same construction and maintenance, but is easier to contamination, equipment tools must be clean.
