Influence of lithium carbonate and superplasticizer as admixtures on low calcium dialuminate cement castable submitted to thermal shock

Journal of Asian Ceramic Societies, 2021
The purpose of this study was to investigate the hot properties of low calcium dialuminate cement castable as binder with varying amount of Li2CO3 and castament FS20 superplasticizer as admixtures. Thermal damage test was carried out through quenching in

Investigation of fracture behavior of typical refractory materials up to service temperatures

International Journal of Ceramic Engineering & Science, 2022
In service, refractory linings experience thermal stresses typically exceeding their mechanical strength. However, this does not lead to the catastrophic failure of modern well‐designed refractory linings. They rather undergo a more or less stepwise wear

Thermomechanical Characterization of Monolithic Refractory Castables [PDF]

Advances in Science and Technology, 2010
This paper deals with the characterization of the thermomechanical behavior of monolithic refractory castables in a wide temperature range, up to 1200°C. Different test types are considered: tensile tests, compression tests, bending tests and tests on more complex shapes and geometries.

Corrosion Mechanism of A Density-Reduced Steel Ladle Lining Containing Porous Spinel-Calcium Aluminate Aggregates

Ceramics, 2020
Refractory monolithics for steel ladle linings are typically products with low porosities and high bulk densities. They achieve high temperature, penetration, and corrosion resistance.

Influence of deflocculants on the cement hydrate phase formation and technological properties of CAC-bonded castables during the first heating process

Open Ceramics, 2023
The mechanism of growth and decomposition of calcium aluminate cement hydrate phases (CAH phases), which determine the drying behaviour of calcium aluminate bonded castables are not well understood.

Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables [PDF]

Cerâmica, 2021
Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of ...
