Comparative study of hydration of monocalcium aluminate
· Monocalcium aluminate (CaAl2O4 CA) and quaternary (Q) phase (Ca20Al26Mg3Si3O68) are the two principal hydraulic phases in calcium aluminate cement. Their strength development has been reported. However little information about the difference of their hydration and hydrates composition is available. For this reason the hydration process of CA and Q phase was investigated and compared.

Refractorinessan overview ScienceDirect Topics
4.12.4.1.4 Refractoriness under load (RuL) RuL is the deformation behavior of a refractory subjected to the combined effects of load time and temperature. Typically the test entails applying a compressive load at elevated temperature to determine the resistance of the refractories to deformation (ISO ). There are two types of RuL test.
