The Hydration Products of a Refractory Calcium Aluminate Cement at Low Temperatures
Calcium aluminates (CA) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements. The anhydrous phases of this kind of cements are CA, CA2 and traces of C12A7 and alpha-alumina. The major hydraulic phase in all of the CA cements including ciment fondu...
متن کاملThe Hydration Products of a Refractory Calcium Aluminate Cement at Intermediate Temperatures
The major hydraulic phase in all the calcium aluminate cements including ciment fondue is CA (CaAl2O4). Once hydrated, it starts to form the hexagonal crystals of CAH10 and C2AH8 that depending on the time and temperature of hydration convert to the cubic crystals of C3AH6 and AH3. The nature, sequence, ...
متن کاملSolubility Product Study of CdF2 in a Mixed Solvent Medium and Related Ion—Pair Formation at 25 °C
The solubility of CdF2 in the mixed solvent (water(1)+ethanol(2)) with mass fraction, W1 = 0.9,was determined by using solvent evaporating method in the presence of various concentrations(0.100, 0.200, 0.300, 0.400, 0.500, 0.600, 0.800 and 1.500 mo1.1)) of NaCI at 25°C. The values ofsolubility and solubility product constant of CdF2 in the mixed solvent were evaluated at zero ionicstrength upon...
