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

open access: yesInternational 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]

open access: yesAdvances 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

open access: yesCeramics, 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 access: yesOpen 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]

open access: yesCerâmica, 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 ...

Deflocculants for refractory castables (review)

open access: yesScientific research on refractories and technical ceramics, 2020
Review and analysis of foreign studies aimed at researching the influence of various deflocculants on properties of refractоry castables have been executed. Technological efficiency of deflocculants application had been shown:– ADS/W brands comparison to polyacrylate and sodium threepolyphosphate in alumina-cement-based mixture in terms mass`s humidity

Effect of Specimen Size on the Resistance to Thermal Shock of Refractory Castables Containing Eutectic Aggregates [PDF]

open access: yesMaterials Research, 2015
Thermal shock is one of the most severe conditions to which a refractory lining can be subjected to during its industrial application. Thus, there are several methods available for testing thermal shock damage resistance of refractories.

The Effect of Deflocculants on the Structure and Physical-Mechanical Properties of Fireclay Refractory Castables

open access: yesMedžiagotyra, 2012
For production of fireclay refractory castables, various deflocculants are used. In recent years new polycarboxylate ethers-based deflocculants appeared and so far their properties comparing to those of common deflocculants are little investigated.
