Refractory Technology 03/09/2020

A. Less shrinkage in heating, decreased apparent porosity & increased specific gravity
B. High strength & thermal spalling resistance
C. Less addition of water to get a workable plasticity & lesser time required for drying the raw
refractories and hence increased rate of production
D. All A., B. and C.
