Aluminate cement is a hydraulic cementitious material formed by calcination with calcium aluminate as the main component and alumina content of about 50%. The main minerals of aluminate cement are calcium aluminate and other aluminates, and a small amount of dicalcium silicate.
Aluminate cement advantage:
1.This series of refractory cement sets and hardens quickly. The intensity can reach more than 80% of the highest intensity, which is mainly used for urgent projects, such as national defense, road and special emergency repair projects.
2.Aluminate cement has heat concentration. The heat of hydration released is 70% ~ 80% of the total amount, which makes the internal temperature of concrete rise higher. Even under -10℃ construction, aluminate cement can soon set and harden, which can be used in winter construction projects.
3.It in the ordinary hardening conditions, because the cement stone does not contain calcium aluminate and calcium hydroxide, and the compactness is larger, so it has a strong resistance to sulfate corrosion.
4.Aluminate cement has high heat resistance. Such as the use of refractory coarse and fine aggregate (such as chromite, etc.) can be made of the use of temperature up to 1300 ~ 1400℃ heat-resistant concrete.
It is worth noting that aluminate cement and portland cement phase mixing not only produce flash coagulation, and as a result of the formation of high alkaline hydrated calcium aluminate, concrete cracking, even destruction, so construction must not be mixed with lime and Portland cement,do not contact unhardened portland cement.
Aluminate cement hardening fast, early strength, high exothermic, water and acid resistance, can not be mixed with limestone, dense impermeability, good heat resistance. Welcome to purchase the needs of users to consult procurement refractory cement.
