Physical and mechanical properties of low cement castable

A castable is a mixture containing gravel and one or more prepared glues. This research studied low-cement castable. X ray diffraction, scanning electron microscopy and spectrography were used to investigate elements and phases. Bulk density, apparent porosity and water absorption were measured. Results show that a castable composed of Bauxite, refractory cement, with suitable q=0.22 in Andreasen Equation for grain size yields the best performance. Bauxite base castable had mullite shape phases inside the pores respectively
