Presented research was intentioned to clarify the effects of thermal treatment (ageing) of reinforcing steel products on their mechanical and deformation properties. In order to determine the effect of temperature, samples were exposed to room temperature (reference samples) and a temperature of 100 °C in duration of 30, 60 and 120 minutes, respect...

This research was conducted in order to evaluate the influence of different curing conditions on rheological and mechanical properties of high volume fly ash concrete (HVFAC) in comparison with the ordinary Portland cement concrete (OPC). Four types of concrete were made: two HVFAC and two OPC designed to have the same consistency and 28-day compre...

The objective of this paper was to assess the possibility of using fine recycled concrete aggregate (RCA) in asphalt mixtures. The experimental research included four asphalt mixtures with partial natural aggregate substitution by fine RCA (0/4 mm), in the amount of 0% (control mixture), 15%, 30% and 45%, by mass. All asphalt mixtures were designed...
