“…In case of the chemical damage (such as leaching), the concrete becomes more porous, facilitating the process of abrasion, and so on. These facts make both processes of deterioration, physical or chemical, a cycle difficult to dissociate or stabilize [2]. Resistance of a particular concrete structure against these types of degradation is influenced by many factors.…”

The paper deals with the use of the abrasive water flow technology in an accelerated simulation of the process of mechanical degradation of surface layers of cement-based composites by flowing liquids. Effects of the abrasive particle size and the mass flow rate of abrasives in an abrasive water flow impacting on the surface of concrete samples have been studied. In addition, suitability of the application of the abrasive water flow for the simulation of real situation of the surface wear by flowing liquids has been evaluated.

Water structures usually consist of concrete surfaces. The concrete surfaces are subjected to erosive wear under the flow of water containing suspended sediment in high concentrations. Such flow-induced erosion is a significant problem for aging structures because it can shorten their service lives. In this study, Bohme, ASTM C 1138 and newly developed Sand-Water Jet abrasion test methods were used to determine the abrasion behavior of different concrete types. Various mineral additives such as fly ash (FA) and blast furnace slag (GBFS) were used to improve the wear resistance of the concrete specimens. In the study, the spillway of the Porsuk Dam from Turkey was chosen as a case study. By taking the spillway concrete recipe of this dam as a reference, its abrasion resistance was analyzed with different mineral-added concrete recipes. According to the results of the study, it was observed that the mixtures using 10% FA and GBFS considerably improved the resistance to abrasion.
