Reduction Rate and Crushing Strength of a Carbon

Feb 23, 2016 The crushing strength and reduction rate of a carbon-containing pellet (composite) prepared from a cold-bonded pellet (CP) and coke oven gas (COG) tar are examined. The peak of the pore size distribution profile, at approximately 2 nm, observed in the as-prepared CP decreases with the increase in the mixture ratio of tar to CP and completely disappears for the composites prepared

Cold Crushing Strength - ReStaR

The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher
