Product description. Aluminite is a refractory cement especially designed to produce refractory and isolating mortars and concretes. Aluminite is made of calcium aluminates and alumina-rich minerals, both milled to the size of microns. By increasing the service temperature, its components are sintered and ceramised, which increases its melting

Abstract This paper re-examines the relationship between durability and conversion of calcium aluminate cement concretes, CACC. Conversion is a natural and inevitable process whereby these materials reach a stable mature condition. Numerous structures built more than half a century ago remain serviceable and in service today.

High-performance concretes from calcium aluminate cements

Calcium aluminate cements have a radically different chemistry to Portland cements. Due principally to their higher cost, they do not compete directly with Portland cements. Nevertheless, concretes based on these cements have very high performance in specific appliions. Two of these are discussed in this article: resistance to acid attack and particularly biogenic corrosion and abrasion

Calcium Aluminate Cement Concrete| Concrete Construction …

Calcium aluminate cement concretes are not rapid setting. They are, however, rapid hardening; that is, they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours, using a water spray or fog, ponding, wet burlap or a curing merane.

Calcium aluminate cements - Wikipedia

Calcium aluminate cements[1] are cements consisting predominantly of hydraulic calcium aluminates. Alternative names are "aluminous cement", "high-alumina cement" and "Ciment fondu" in French. They are used in a nuer of small-scale, specialized appliions.

Calcium Aluminate Cement – Royal White Cement

Calcium aluminate cement is cement formed from the coination of limestone and alumina at high temperatures. It is used in specialized cement appliions where resistance to extreme temperatures, mild acids and alkalies, sulfates and water are necessary. It is also used in situations where rapid strengthening is required.

Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements (CACs) represent an interesting alternative because their pore water pH, ranging from 11.4 to 12.5, is reduced as compared to OPC (Goñi et al., 1991). The main difference between Portland and calcium aluminate cements lies in the nature of the active phase that leads to setting and hardening.

Calcium aluminate cement concrete

Calcium aluminate cement concretes are not acid p r oof, but they are resistant to the corro s i v e effects of c e r tain acids and industrial wastes. They can be used to resist corrosion down to a pH of about 3.5 to 4.0, de-pending on type of acid, tempera t u re
