Implementation of industrial waste ferrochrome slag in conventional and low cement castables: Effect of calcined alumina

Journal of Asian Ceramic Societies, 2014
A new class of conventional and low-cement ferrochrome slag-based castables were prepared from 40 wt.% ferrochrome slag and 45 wt.% calcined bauxite. Rest fraction varied between high alumina cement (HAC) acting as hydraulic binder and calcined alumina ...

Influence of the type of phosphate additive and its concentration on the setting kinetics of CA cement bonded refractory castables with special regard to the resulting pH value

Open Ceramics, 2023
During the hydration of CA cement exists a dormant period, which is responsible for the setting kinetics of CA cement bonded refractory castables. The dormant period is believed to be caused by an Al–O–H passivation layer on the CA cement particles ...
