High Alumina Mortar in Pakistan

June 16, 2021December 3, 2019 by rsrefractorycastable

High alumina mortar is mainly calcium aluminate, alumina content of about 50% clinker, belongs to aluminate cement. High alumina mortar advantage outstanding, it belongs to hydraulic cement, the main mineral composition is calcium silicate.

High aluminum mortar advantage

High alumina mortar advantage:

1. Fineness: the finer the cement particles are, the larger the specific surface area is, the faster and more sufficient the hydration reaction is, and the earlier and later the strength is higher.

2. Setting time: in order to ensure that there is enough time in the construction to complete the mixing, transportation, molding and other processes, the cement initial setting time should not be too short; After construction, hope cement can harden as soon as possible, produce strength, so final setting time should not be too long.

3. Volume stability: the uniformity of the volume of cement slurry during the setting and hardening process is called volume stability of cement. If the volume change is not uniform, that is, the volume stability is poor, prone to warpage and cracking, reduce the quality of engineering and even accidents.

High alumina refractory mortar lining for baking, to pay special attention to the slow baking. If there is still a lot of steam coming out after 350 degree heat preservation, the heating rate should still be slowed down. Under the condition of poor ventilation and difficult discharge of water and gas, the insulation time should be extended appropriately. And when baking with heavy oil, to prevent heavy oil spray in the furnace lining surface, in case of local blowout. When using wood to bake, direct contact with the flame often causes local heating too urgent, should be protected. Still have the cooling that is to refractory cement furnace lining also should slow, avoid forced ventilated.

The high alumina mortar advantage is obvious, because it has excellent characteristics of quick setting, high strength, high temperature resistance, one day strength can reach 80%, fireproof can reach 1450 degrees, fireproof concrete strength can reach 55MPa, is one of the excellent high temperature binder materials in industrial kiln engineering. High aluminum mortar is the main raw material for preparing unshaped refractory. Gypsum bauxite expansive cement, self – stress cement and other special purpose cement. It also plays an important role in construction, repair, resistance to sulfate erosion and winter construction.

High Alumina Cement Made in China

June 16, 2021November 29, 2019 by rsrefractorycastable

The high alumina cement manufacturing is a cementitious material with the properties of fast hardening, high strength, heat and corrosion resistance. Where the calcium aluminate based, alumina content of about 50% of the clinker, grinding hydraulic cementitious materials, known as high aluminum cement. Mainly used for urgent projects, such as pressure prevention, road and special repair projects, can also be used for winter construction projects.

As is known to all, high aluminum cement is made of bauxite and lime as raw materials, in accordance with a certain proportion of preparation, after calcining, grinding made of a kind of aluminate as the main mineral composition of hydraulic cementitious materials, also known as aluminate cement.

In the high alumina cement manufacturing, the heating temperature and the time to reach the highest temperature of the single pouring body of different kinds of high alumina cement are determined by the heating characteristics and content of the calcium aluminate contained in the pouring body. Fast C12A7 and C4AF have higher calorific value. Therefore, the calorific value of high aluminum cement will also contain the aluminate different and change. So, the quantity that chooses refractory cement and quality are very important.

High alumina cement characteristic:

1. Early strength characteristics: its early strength increase rate is much higher than fast hard Portland cement, suitable for emergency repair engineering, but later strength will be reduced, limit the use in structural engineering.

2. Hydration heat is larger: early cement hardening heat release, and with the same label Portland cement, only a day can give out 70~80% of the total hydration heat. Due to several exothermic heat, it is suitable for low temperature curing concrete engineering.

3. Strong sulfate resistance: the hydration process does not precipitate free calcium hydroxide but produces aluminum hydroxide gel, forming a protective film on the particle surface. The corrosion resistance was decreased during the later crystal transformation.

4. High temperature resistance: high aluminum cement can be used as the cementing material of heat resistant concrete, configured into heat resistant concrete.

High aluminum castable refractory sales, characteristics, simple production process, convenient construction, high temperature structure strength, acid and alkali chemical erosion resistance.

This series of refractory castable is to add micro-expansion agent in the preparation process of ordinary high aluminum castable, and use the principle of irreversible expansion of bluestone in high temperature to prevent shrinkage of pouring liner and improve the air tightness of the whole structure.

High alumina castable refractory sales, construction water consumption is low, so it has a high density and low porosity. High alumina castable has good volumetric stability at high temperature. Although it is a non – burning refractory, its volume decreases after drying and calcination. It not only has higher curing strength at room temperature, but also does not reduce the strength after medium and high temperature treatment. The absolute strength is 3-5 times of that of traditional refractory castable. The content of calcium in castable is only 1/4 to 1/3 of that of traditional castable. Thus, the number of low melting phases in refractory castable is reduced, resulting in a significant improvement in high temperature function.
