Abstract
It is generally known that the properties of concrete, particularly the strength, vary depending on the concrete age due to the chemical-mechanical processes occurring in the structure of concrete during ageing (maturing). The issue often is the time needed for concrete to reach its desired safety before a concrete structure made of fresh concrete can be partially or completely loaded. In structures coming into contact with flowing liquids, the resistance of surface layers to erosion caused by abrasion or cavitation is also important, in addition to the strength. Therefore the analysis of effects of the concrete age from 7 days to 1 year on the concrete resistance to fast-flowing liquids is the subject of this paper. A method of accelerated hydraulic-mechanical simulation of the surface layer loading by means of a pure high-speed water jet and a water jet with abrasive particles was used in order to investigate the concrete erosion resistance. The influence of the concrete age on the resistance to fast-flowing liquids has been proven. After a year, the concrete resistance increased by about 36% in the case of the pure water jet, and 28% in the case of the abrasive water jet.
