Permeabilidade de concretos refratários multifuncionais Permeability of multifunctional refractory castables

Cerâmica, 2001
Concretos multifuncionais oferecem como principal vantagem a possibilidade de aplicação do material refratário através de diversas técnicas de instalação (p.e. socagem, vibração, projeção, auto-escoamento) variando-se apenas o teor de água.

Reasons for crack propagation and strength loss in refractory castables based on changes in their chemical compositions and micromorphologies with heating: special focus on the large blocks

Journal of Asian Ceramic Societies, 2019
Among the most significant problems in industrial refractory manufacture, especially of monolithic refractories, are the formation of cracks and loss of strength in green bodies or during heating of the refractory castables.

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 ...

Mullite macro-needles for reinforcement of refractory castables

Cerâmica, 2022
Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase.
