Supercritical carbonation of calcium aluminate cement
Cement and Concrete Research, 2008 The microstructural changes occurring during supercritical carbonation (scCO2) of calcium aluminate cement (CAC) and changes to its strength have been investigated. Cylindrical specimens of CAC cured at different temperatures were prepared and then subjected to scCO2.

Impact of slag on carbonation rate of concrete based on calcium aluminate cement [PDF]
MATEC Web of Conferences, 2022 Throughout their service life, concrete structures are exposed to various environmental conditions that affect their durability. The cementitious matrix inevitably comes into contact with air, which leads to a progressive carbonation reaction.

Strontium in Phosphate-Modified Calcium Aluminate Cement
Key Engineering Materials, 2019 Cements have been used to encapsulate low and intermediate level radioactive wastes. Here, phosphate-modified calcium aluminate (CAP) cement is explored as an encapsulant for strontium radioanuclide-containing wastes. Electron microscopy indicates strontium chloride, used in place of strontium radionuclides, increases porosity in CAP possibly due to ...
