A. Modulus of rupture
B. Permanent linear change
C. Resistance to CO attack
D. RUL
A. Beehive oven
B. Coke oven walls
C. Zinc roaster
D. Lead blast furnace
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.
A. Porosity
B. Specific gravity
C. Thermal conductivity
D. Strength
A. Basic Bessemer converter
B. Basic open hearth furnace
C. Electric furnaces
D. All A., B. and C.
A. Refractoriness (< 1700°C)
B. Thermal conductivity
C. Resistance to thermal shock
D. None of these
A. Acidic in nature
B. Neutral in nature
