Calcium Aluminate Cement

Description of Calcium Aluminate Cement

Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The high temperature alumina cement obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. The aluminate cement has the ability to harden very quickly: it forms a rigid solid within 24 hours.

Application of Calcium Aluminate Powder

There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries.

As binders, calcium aluminates are used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations.

Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, the calcium aluminate powder acts as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix.

As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.

Calcium Aluminate Cement Construction Method:

2. ' s hydration heat concentrate on early stage. Casting thickness should not exceed 3 cm each time. Water curing immediately when concrete goes hardening and the curing time should not less than 3 days.
3. ' s dosage is 73-76%, CaSO4·2H2O dosage is 24-27%. When prepare self-stressing cement, the mixing ratio of CaSO4·2H2O should be increased.

Calcium Aluminate Cement Notice:

1. 2. Steam curing to accelerate concrete' s hardening. The curing temperature of aluminate cement should not higher than 50℃.3. Refractory concrete' s late strength decline big, design should according to the lowest stable strength. CA-50 bonded concrete' s lowest stable strength should be determined by the lowest strength of 7-14 days of demoulding sample curing in 20℃±1℃ water.Calcium Aluminate Cement Packing:by 50kgs bag. Store in shady, cool and dry place. Avoid stamp and mix with other substance.Where toBuy Calcium Aluminate CementWe are professional in calcium aluminate cement manufacturing process andproduce excellent calcium aluminate cement, high alumina cement and high temperature alumina cement supplier, please feel free to contact us for calcium aluminate cement price.
