EL70 is calcium aluminate cement obtained from fusion of high purity bauxite and calcium carbonate in electric arc furnaces. It is ball milled with alumina addition which makes EL70 an ideal product for special refractory appliions. It comes in three versions (Gun, E, and N) with varying set times, depending on the appliion.

Cements high in aluminate phases hydrate to form products that are different to those of OPC. In all calcium aluminate cements, monocalcium aluminate (CA) is the major component which reacts with water to form a series of calcium aluminate hydrates. At low temperatures (< 18°C) these are an alumina gel and CAH 10, whilst

High Alumina Cement (HAC) differs from Portland cement, being composed calcium aluminates rather than calcium silies. Its rapid strength development made HAC popular from 1950 to 1970. However, mineralogical ´conversion´ sometimes caused reductions in concrete strength and increased vulnerability to chemical attack.
aluminate binders and calcium aluminate bonded highperformance monolithic castables by C. Parr*, H. Fryda*, and Ch. Wöeyer* Synopsis Monolithic refractory castables, bonded with calcium aluminate cements (CACs), have a rich history of nearly 90 years. They have evolved from highcement conventional formulations to the era of
Calcium aluminate cements (or highalumina cements) are a group of hydraulic binder of the cement family, containing different amounts of alumina ranging from 38% up to about 95%, which are manufactured by either fusing or sintering a proportioned mixture of limestone and bauxite.
· Calcium aluminate cements (CACs) are chiefly utilized as binder in monolithic refractories. Further appliions of CACs are industrial flooring products (like cast house floors), concretes and mortars resistant to chemicals, sewer appliions, expansive grouts, tile adhesives, protective coatings, floor screeds, and building chemistry products (CAC is mixed with OPC to ensure .
Traditionally, calcium aluminate cements (CACs) are produced by fusion or sintering using precursor sources of high alumina and limestone with acceptable grades of impurities. The main impurities are silica, ferrites, magnesia, titania and alkalis. Due to the production conditions and raw materials compositions, CACs can be obtained
High alumina refractory cement (HAC) are essentially those, which contain calcium aluminates as primary hydraulic constituent. Among the calcium aluminate phases monocalcium aluminate ( 2 O 3) is the most desirable one since it imparts both high early strength as well as high refractoriness.
· High Alumina Cement (HAC, sometimes known as calcium aluminate cement (CAC) or aluminous cement) is composed of calcium aluminates, unlike Portland cement which is composed of calcium silies. It is manufactured from limestone or chalk and bauxite.

This study investigated the influence of limestone (LS) and calcium sulfate (C) mineral additives on the hydration kinetics of highαAl2O3 calcium aluminate cement (CAC) utilizing experimental techniques and thermodynamic simulations. Increasing the replacement level of limestone or calcium sulfate increased the cumulative heat of the hydration reaction.
High Alumina Cement. High Alumina Cement (HAC) differs from Portland cement, being composed calcium aluminates rather than calcium silies. Its rapid strength development made HAC popular from 1950 to 1970. However, mineralogical ´conversion´ sometimes caused reductions in concrete strength and increased vulnerability to chemical attack.
duced by the interaction of high pressure H20, CO, and CO2 with some of the phases forming th e hot castable high purity calciu m aluminate liner material found in many operating coal gasifiers. The principal constituents of this castable liner material are calcium aluminates and alumina. 2.
What is Calcium Aluminate Cement. Calcium Aluminate Cement is a hydraulic binder with normal setting and rapid hardening obtained by finely grinding the resulting product of the combustion mixture of limestone and bauxite. Bauxite is a hydrated aluminum trioxide (Al2O3. NH2O) that contains impurities of silicon dioxide and iron trioxide.
High Alumina Cement / Calcium Aluminate Cement. We make two types of Calcium Aluminate Cements (High Alumina Cement), HCEM50 both of our brands (HCEM50 and HCEM70) are famous and recognised globally for high quality and best physical properties.
CSA Cement, Calcium Aluminate Cement, High. Calcium Aluminate Cement is also called high alumina cement and refractory cement. It is mainly used to produce selfleveling mortars due to its good fluidity, fast setting time, and high strength.
Calcium aluminates (CAC) may go under the other names of aluminous cement or high alumina cement (HAC). Calcium aluminate cements evolved from a drive to develop sulphate resistant cements. Some of the notation used later in this article uses cement chemistry nomenclature, which is documented in table 1.
Refractory cement made up of calcium aluminates and aluminarich materials with high compressive strength and high refractoriness. Its main constituents are: 1. Calcium Aluminate Cement clinker Calcium Aluminate Cement clinker is produced by fusing or sintering a precisely specified mixture of aluminous and calcareous material.
