You can visit for our new product family. EL-70 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 EL-70 an ideal product for special refractory applications. It comes in three versions (Gun, E, and N) with varying set times, depending on the application. Product Concrete pipes for sewerage can be made either with full mass calcium aluminate cement concrete or with an internal liner of calcium aluminate cement mortar, Rehabilitation of man-accessible sewer infrastructures with 100% calcium aluminate mortar using one of the following installation methods: low pressure wet spray, spinning head wet spray or high pressure dry spray (gunite). Today, thanks to one and half decade of experience, the company enjoys leadership status in the field of Alumina Trihydrate, Calcined Alumina, Sodium Aluminate, Activated Alumina. Now we introduced our new product calcium Aluminates Cement containing 80% Alumina, a substitute for imported cement.

HYDRATION OF CALCIUM ALUMINATE CEMENT PHASES CA AND CA 2 IN REFRACTORY APPLICATIONS Sebastian Klaus 1, Andreas Buhr , Dagmar Schmidtmeier 2, Stefan Kuiper 3, Friedlinde Goetz-Neunhoeffer4 1Almatis GmbH, Frankfurt, Germany, 2Almatis GmbH, Ludwigshafen, Germany, 3Almatis BV, Rotterdam, The Netherlands, 4University of Erlangen-Nürnberg (FAU), GeoZentrum Nordbayern, … Calcium aluminate cement (CAC) has been widely applied in many industrial applications owing to its advanced properties, such as suitable rheological properties for workability in refractory castables, outstanding green mechanical strength and resistance to a wide range of chemically aggressive conditions [1–4]. Nevertheless, one of the Select from the broad varieties of raw ca50 calcium aluminate cement on for industrial uses. These efficient ca50 calcium aluminate cement are used in steel and cement-making processes. The phase formation, heat of hydration and dilatation in a blended cement consisting of 50 wt.% calcium aluminate cement, 25 wt.% Portland cement and 25 wt.% calcium sulfate were studied (w/c=1). We are a cement supplier, dealing in fields of special cements, refractory materials and ore products.

Calcium aluminate cement are applied widely in various high temperature industries as refractory materials, for monolithic uses.


In calcium aluminate cements, it exists as a solid solution in which the amount of minor elements depends upon the bulk composition of the cement. A typical composition is … Calcium aluminate cement (CAC), mainly consisting of monocalcium aluminate (CA), has been used in the construction industry since the late 19th and early 20th centuries after patented in … The properties of some high‐purity calcium aluminate cement compositions in that portion of the lime‐alumina system from 64 to 86% alumina were investigated.

Calcium Aluminate Cement Conferences. Since its invention in 1908 Calcium Aluminate Cement has been the subject of much research both in the context of the pure calcium aluminate systems but also systems in which the various attributes of calcium aluminates play a key part and in 1982 an international seminar was organised in Turin, Italy to discuss research findings of leading experts from 2017-01-30 · Calcium aluminate cement (CAC) suffers from loss of workability in less than an hour (~15 minutes) after first touch of water. Current superplasticizers that are utilized to modify the viscosity Se hela listan på In the present study, the development of strength in different calcium aluminate cement (CAC) mixture mortars with granulated ground blast-furnace slag (GGBS) was investigated. The substitution of GGBS levels was 0, 20, 40, and 60% weight of binder, of which the CAC used in this study naturally contained C2AS clinker as a secondary phase.
