Abrasion Resistance of Concrete in Hydraulic Structures

The analysis showed a qualitative similarity of the level of abrasion of concrete between laboratory simulations and measurements in the field, as well as suitability of the ASTM C1138 laboratory method for the assessment of abrasion resistance of concretes in the spillway of the hydro power plant chain on the Lower Sava River

  • Abstract:In this paper, the phenomenon of concrete abrasion in hydraulic structures, which is caused by the abrasion process resulting from the sediment carried by water, is analyzed
  • The adequacy of the laboratory procedure for the definition of the level of concrete abrasion in standard ASTM C1138 hydraulic structures was investigated in detail
  • The concrete built in the evacuation structures of the hydro power plant on the Lower Sava River was tested for adequacy
  • The basic composition of concretes was modified by polymer or pozzolanic additives along with the primary binder, steel fibers, polypropylene fibers, and granular rubber
  • The analysis showed a qualitative similarity of the level of abrasion of concrete between laboratory simulations and measurements in the field, as well as suitability of the ASTM C1138 laboratory method for the assessment of abrasion resistance of concretes in the spillway of the HPP chain on the Lower Sava River
