Calorimetric study of calcium aluminate cement blended
Jun 19 2009 · Abstract. The use of by-product gypsum is an important alternative in concrete design. In present experiment conduction calorimetry was applied to investigate the early hydration of calcium aluminate cement (CAC)/flue gas desulfurization (FGD) gypsum paste supplemented with the determination of setting times and analysis of hydrates by X-ray diffraction (XRD).

Calcium Aluminate Cement for corrosion resistant sewer
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.

Sealing properties of a calcium aluminate luting agent
Purpose To determine the self-sealing properties of Ceramir C B a new calcium aluminate-based luting material and to compare it to two commercially available cements using a bacterial model system. Methods 30 premolars were prepared in a standardized fashion with a total angle of convergence of approximately 10-12 degrees for complete cast restorations.
