This work covers some workability, mechanical, and durability properties of coloured self-compacting concrete SCC containing maroon marble powder and iron oxide pigment. Pigments with varying amounts were used to produce coloured SCC. For this purpose, ten different series were prepared of which two of the series were pigment free that one of them was the colour of white SCC including ...
2020-6-12The resistance to abrasion is calculated as the abrasive loss in mass per film. This Falling Sand Abrasion Tester is designed and engineered in accordance with International Testing Standards, e.g. ASTM D968 Standard Test Methods for Abrasion Resistance
Essentially the process of Hardfacing or Surfacing consists in depositing a welded overlay, providing hardness, abrasion-, erosion-, galling-, impact-, corrosion- or heat resistance as required.. The original or the worn out surface becomes covered with new, harder material, so that it might better perform its function in a harsh environment, for longer time with less maintenance.
