Research has shown that on a total fused calcium aluminate concrete surface, bacteria experience a lower activity than on a portland cement concrete surface, based on the observations of the pH level measured on the concrete surface and the materials.
Here, phosphate-modified calcium aluminate (CAP) cement is explored as an encapsulant for strontium radioanuclide-containing wastes. Electron microscopy indies strontium chloride, used in place of strontium radionuclides, increases porosity in CAP possibly due to …
Isothermal Conduction Calorimetry Study of Class G Oilwell Cement Hydrated with Additions of Calcium Chloride, Calcium Formate and Sodium Aluminate at Low and Aient Temperatures Lota, J. S. / Bensted, J. / Pratt, P. L. | 2003
The present study concerns a development of calcium aluminate cement (CAC) concrete to enhance the durability against an externally chemically aggressive environment, in particular, chloride-induced corrosion. To evaluate the inhibition effect and concrete properties, CAC was partially mixed with ordinary Portland cement (OPC), ranging from 5% to 15%, as a binder. As a result, it was found

The aim of this study is to investigate the durability of geopolymer mortars based on waste-glass powder (WGP) and calcium aluminate cement (CAC) exposed to acid attack. Geopolymer specimens were prepared by a coination of WGP and CAC activated by an aqueous solution of sodium hydroxide and sodium silie and were cured under hydrothermal conditions.
