Calcium aluminate cements - Wikipedia

Calcium aluminate cements 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 number of small-scale, specialized applications. History. The method of making cement from limestone and low-silica bauxite was patented in France in 1908 by Bied of the Pavin de Lafarge ...

Calcium Aluminate Cement for corrosion resistant sewer ...

01/10/2020  Mix CAC 45 contains Calcium Aluminate Cement and has the lowest mass loss of all samples. The better buffer capacity by means of pH values confirms the higher biogenic corrosion resistance. Whilst the pH of OPC-based mixes descends to around 1, CAC 45 mortar stabilizes between pH 2 and 4. The CAC substrate inhibits bacteria colonization, thus limiting sulfuric acid production.

HIGH PERFORMANCE CALCIUM ALUMINATE CONCRETES

A BRIEF HISTORY OF CALCIUM ALUMINATE CEMENTS (CAC) High alumina cement is not a recent development. It was discovered in France as long ago as 1865 that fused and crushed mixtures of alumina and lime have hydraulic cement properties. In 1888 a patent was issued in the United Kingdom for limestone bauxite cement. It was not until the beginning of the twentieth century that high alumina

In sewer environment, calcium aluminate cement (CAC) based materials are more resistant than ordinary calcium silcate cement based materials [2,3]. This higher resistance is commonly explained by the content of aluminium inducing a bacteriostatic effect and/or the physico-chemical properties of CAC (neutralisation capacity, porosity, phase stability) [4].
