Physical and mechanical properties of low, ultralow and no cement refractory castables containing MgO nanoparticles developed in situ by means of polymeric resins [PDF]
The introduction of MgO nanoparticles developed in situ in the matrix of high-alumina low cement, ultra-low and no cement refractory castables was made by means of a low viscosity containing aqueous polymeric resin, produced by the Pechini method.

EFFECT OF STEEL FIBERS ON REFRACTORY CASTABLES
Reinforcement of refractory castables with steel fibers improves their strength for cracking and spalling and expands the service life. The results show that raising the temperature from 700°C to 900°C causes an increase in porosityand decrease in ...

Mullite macro-needles for reinforcement of refractory castables [PDF]
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.

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