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.

We supply the calcium aluminate as clumps or grains, so that dust pollution is greatly reduced. Our pre-fused clinker has a low melting point, meaning quick melting speed, good liquidity, lubriion and high efficiency for desulphurization.

MODIFIION OF OXIDE INCLUSIONS BY CALCIUM TREATMENT IN SI-KILLED STEEL …

Calcium modifies solid alumina inclusions, arising out of deoxiclation of liquid steel, into liquid calcium aluminate. Depending upon the steel composition, calcium sulfide (CaS) and/or various

Calcium wire ladle treatment to improve cleanliness of centrifugal cast steel

It was found that the efficiency of calcium wire fed just prior to casting was slightly higher than calcium fed at earlier stages of the ladle treatment (just after AOD), providing better Ca- reactions with the melt. Alumina (Al 2 O 3) inclusions were transformed into low
