As the name suggests High Alumina Cement differs from Portland Cement in as much as it is made up of calcium aluminates as opposed to calcium silicates. This allows rapid strength gain and led to its popularity in building construction during the 1950’s to 1970’s.
What is HIGH-ALUMINA CEMENT? Cement containing a higher proportion of alumina 30-50% than ordinary Pordand cement, it is faster setting, less affected by low temperature during setting, and more resistant to seawater and acids when set. But it has been found to degrade in warm, humid environments, eg swimming pools.
Addition of CEMDY50 to Portland cement will accelerate the initial set. It can be used in combination with other reactive minerals to form the binder in many formulations for fast setting patch materials, non shrink grouts etc. 2.

There are also some other materials such as high alumina cement, silica fume, alumina powder and bauxite fine powder.And they are mixed with a certain of proportion according to various construction demand.
The process of manufacture of High Alumina Cement is different compared to that of ordinary portland cement. Bauxite and lime are used as the raw material. The raw materials are mixed in the required proportion and grinded into small fragments of 100 mm. These lumps are fed in kiln and heated up-to ...
High-alumina cement, * aluminous cement, or calcium aluminate cement is a hydraulic cement, characterised by having monocalcium aluminate (Ca0.A120,) as the main cementitious ingredient. Since 1865 it has been known that calcium alum- inate would set and harden to great strength when ...
High Alumina Cement (HAC, known as calcium aluminate cement (CAC) or aluminous cement) is mineral of amorphous calcium aluminate (non-crystalline calcium aluminate). Oreworld Trade is a professional high alumina cement suppliers.
Sep 19, 2018· In addition to the general cement of the hydraulic gelling performance, the most is the quick and hard heat; (1) the production of fast-hard concrete and fast-hard mortar: high-alumina cement hydration early high strength, one day the strength of up to 70% of the label, it can produce fast-hard concrete and heat-resistant mortar.
Physical Properties of High Alumina Cement: The high alumina cement is black in colour and its rate of strength development is very high. About 80% of its ultimate strength is developed at the age of 24 hours Even 8 hours strength is sufficient for the removal of the form work. The high rate of gain of strength is due to its rapid hydration.
HIGH ALUMINA CEMENT. These are calcium aluminate cement binders produced by sintering method from a mixture of aluminous and calcareous materials. These products is used for making refractory castables after proportioning with selected refractory aggregates in various combinations to get specific high-temperature properties.
High Alumina Cement. Alumina cement is an inorganic material that form a dense texture when it reacts with water. It has excellent refractoriness, quick hardening and resistance to chemical attacks. Our high alumina cement is widely used for the production of high quality refractory castables and other special materials.
