On the benefits of correcting brightness and contrast in global digital image correlation: Monitoring cracks during curing and drying of a refractory castable

Optics and lasers in engineering, 2021
The gray level conservation is the underlying hypothesis of Digital Image Correlation (DIC). However, it may be challenging to enforce in some experimental configurations.

A simple methodology based on numerical analysis for the drying curve design of a castable lined steel ladle

Open Ceramics, 2023
Energy efficiency is closely linked to industry goals of reducing environmental impacts, where selecting the best heating curve has a great effect on the total energy consumption, costs, and CO2 emission, especially for refractory castable lining ...

Investigation of the milling route for the development of colloidal suspensions to be used as binder in refractory castables

Open Ceramics, 2023
Refractories castables bonded with CAC (calcium aluminate cement) have a limitation when they are used at high temperature in micro-silica containing system and/or in acidic corrosive environments.

Phase Transformations and Properties Evolution of Alumina-Based Refractory Castables Containing ZnO and SiO2

Materials Research, 2022
Although most of the studies presented in the literature are focused on MgAl2O4 formation and its role on alumina-based refractories performance, ZnO has been reported as a promising spinel inducer. Aiming to investigate the influence of ZnAl2O4 (ZA) and

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.
