Nov 03, 2009· The stronger a material is the greater is the resistance to abrasion. Also stronger refractories are expected to have higher resistance to slag attack. The determination of cold crushing strength (CCS), however, is highly important in case of refractory insulating bricks where bricks have to be porous as well as strong.

Aug 24, 2021· Aug 24, 2021· The crushing or compressive strength of normal building bricks should not be below 3.5 N/mm². The bricks of high quality should not have strength below 14 N/mm².

silica. The total silica content of a rock issilica. The total silica content of a rock is decisive for its abrasive properties: The higher the silica content, the higher the wear on the crusher liners. From experience we know that there is a approximate relationship between the Abrasion Index AI and the silica content of the materialthe material.
