Binders for Refractory Castables: An Overview
Interceram - International Ceramic Review, 2020Abstract: A binder for refractory castables is a bonding material that bonds a loose powdery mix, retains its shape after casting and allows the cast shape to set and harden for handling and further processing. A binder also improves sintering, as the castables are not compacted during shaping, causing poor densification and strength.

Novel drying additives and their evaluation for self-flowing refractory castables [PDF]
Ceramics International, 2020 The drying step of dense refractory castables containing hydraulic binders is a critical process, which usually requires using slow heating rates due to the high explosion trend of such materials during their first thermal treatment.

Gas permeability of alumina‐spinel refractory castables bonded with hydratable magnesium carboxylate
Journal of The American Ceramic Society, 2023The high level of gas permeability can effectively reduce the explosive spalling risk of refractory castables. The hydratable magnesium carboxylate (HMC) is expected to improve the permeability of castables owing to the thermal decomposition of the HMC ...

REINFORCEMENT BONDING PERFORMANCE IN REFRACTORY CASTABLES UNDER ELEVATED TEMPERATURES
Proceedings of International Structural Engineering and Construction, 2022Refractory castables, representing a mixture of a refractory aggregate, calcium aluminate cement, ultra-fine particles, and deflocculants, have been created in the mid of past century ’80s for the metallurgy and petrochemical industries.

To achieve better performance of bauxite-corundum refractory castables in the steelmaking industry, we developed two reinforcement approaches (i.e. by removing microsilica or replacing cement with microsilica) for this refractory in this work. Besides, a

Hydratable magnesium carboxylate (HMC), which is similar to the properties of cement, can be used as a potential binder for refractory castables. However, its decomposition may lead to poor mechanical properties at medium temperatures (300°C ∼ 1100°C ...

Aluminum lactate role in improving hydration and drying behavior of MgO-bonded refractory castables [PDF]
Ceramics International, 2020 Developing MgO-bonded castables is still an important subject for refractory producers and end-users based on the expansive character of the in-situ Mg(OH)2 formation.

Drying behavior of steel-ladle lining refractory castables under continuous heating rate
Ceramics International, 2021The current trend to replace shaped refractories for monolithics is related to various technical aspects, i.e., lack of joints, easier installation and free format.
