Alumina Cement Manufacturer

Aluminum cement is a hydraulic cementation material made of high alumina or industrial alumina and calcium carbonate (limestone) in a certain proportion, calcined or electrofused clinker made of calcium aluminate as the main component, alumina content more than 50%, and then ground. The series of refractory cement is usually yellow or brown, but also gray. The main mineral components of alumina cement manufacturing are monocalcium aluminate and other aluminate, and a small amount of dicalcium silicate, etc. It has a high refractory temperature and stability, and is often used as a binder for unshaped refractory materials.

    Alumina Cement Application

    1. Binder for unshaped refractory materials;

    2. Alumina cement manufacturing has high heat resistance, and refractory thick and fine aggregate (such as chromite, etc.) can be made into high temperature resistant (1300 ~ 1400℃) heat resistant concrete;

    3. It is used for construction emergency works. Aluminate cement is fast in setting and hardening, and its 1D strength can reach more than 80% of its strength. It is mainly used for emergency projects within construction period, such as national defense, roads, special emergency repair works (leak plugging) and temporary works.

    4. High alumina cement is mainly used in sulphate corrosion resistant engineering. It has strong resistance to sulfate corrosion under ordinary hardening conditions, because the cement stone does not contain tricalcium aluminate and calcium hydroxide, and the density is large.

    5. This series of refractory cement can also be used in winter construction. Aluminate cement has high hydration heat and concentrated heat release. The heat of hydration released within 1d is 70% ~ 80% of the total amount, which makes the internal temperature of concrete rise higher. Even under -10℃ construction, aluminate cement can set and harden quickly, which can be used for winter construction.

    Alumina Cement Advantage

    1. It has stable performance, high strength, fast generating strength and strong applicability.

    2. Can also be used to prepare refractory castable, prepared low cement refractory castable, light refractory castable, refractory spray coating and other indeterminate refractory materials.

    3. High alumina refractory cement can be used to produce precast refractory blocks, slag balls and other shaped refractory materials.

    4. Prepare temporary fast construction, rush repair, support concrete, prepare sulfate resistant mortar and other building materials.

          Feature and Application Of Alumina Cement

          1. Fast hard early strength, early strength growth fast, suitable for emergency repair engineering and early strength requirements of high engineering. The late strength of high alumina cement may decrease, especially in the humid and hot environment above 30℃, the strength will decline faster, and even cause the destruction of the structure. Therefore, the use of aluminum cement in structural engineering should be cautious.
          2. Alumina cement hydration heat, and will be concentrated in the early release. It is suitable for construction in winter, not for mass concrete project and high temperature and humidity environment.
          3. This series of refractory cement has good resistance to sulfate attack. The main component of alumina cement manufacturing is low calcium aluminate, free calcium oxide is very few, cement stone structure is relatively close. Therefore, it is applicable to the engineering required to resist sulfate erosion.
          4. High alumina cement in contact with alkaline solution, even when the concrete aggregate contains a small amount of alkaline compounds, will cause erosion. So it can’t be used for projects that touch alkaline solutions.
          5. Good heat resistance. Alumina cement manufacturing at high temperature will produce a solid reaction, sintering bonding instead of hydration bonding, so that high aluminum cement at high temperature can still maintain high strength.

            High alumina cement has a high degree of hydro-hardening activity, usually the hardening time is not more than 1 day, high alumina cement is the main source of the early strength of refractory prefabricated parts. This series of refractory cement has the effect of making the cement harden as early as possible, and in the advanced alumina cement also plays a hardening role, also plays a crucial role in the later strength. The heating temperature and the time to reach the highest temperature of the single cast of different kinds of high alumina cement are determined by the heating characteristics and content of the calcium aluminate contained.
