Furthermore, the effects of the interface property distributions on the load/displacement curve, fracture energy, cold crushing strength, and fracture events were investigated. The results reveal that the DE method is a promising method for visualizing and quantifying the post–peak fracture process and crack events in ordinary refractory ...

In another study, Hubalkova and Stoyan reported that the cold crushing strength of high alumina refractory castables is influenced by the spatial arrangement and shape of aggregates [5]. Heindl and Mong [6] examined 22 brands of common refractory ceramics from 10 manufacturers, which were prepared by dry-press, stiff-mud or handmade processes.

According to the standard the cold crushing strength, (CCS) gunned type, the values are between 28.00 to 55.00 Kg.cm-2 [5], then it can conclude that the cold crushing strength (CSS) of SRM passes the limited standard. Agreement with CSS, the flexural strength values increase with cured time. The maximum value is 4.53 Kg.cm-2 at cured time of 28

ABSTRACT The present study demonstrates the effect of the different morphological types on the cold crushing strength (CCS) of heat-treated iron ore pellets. Blends with different iron ore oxides morphologies were subjected to grinding, filtering and pot grate tests on industrial scale trials. Results of grinding tests showed the hematite-goethite aggregates …

When the amount of iron ore was 30%, the crushing strength of ferro-coke dropped to 18.15%. Among the four binders, coal tar pitch could significantly enhance the cold crushing strength of ferro-coke through decreasing the porosity of ferro-coke and improving the bonding effect between carbon matrix particles.

McDowell and Amon (2000) have found that the particle crushing strength of geometrically similar particles follows a Weibull distribution, written as (A.4) P s = exp − d s d 0 3 σ σ 0 m, where P s is the breakage ratios under the corresponding load, d 0 and σ 0 are the characteristic diameter and crushing strength, respectively.
