EFFECT OF THE HRWRA QUANTITY ON DURABILITY PROPERTIES OF SELF-COMPACTING CONCRETE
The paper presents the results of our own experimental research on the effect of the high range water reducing admixture content – HRWRA (applied in the range from 0.8 to 1.2% by mass of cement – mc) on the properties of self-compacting concrete in the fresh and hardened state. The research showed that increasing the HRWRA content lead...

THE EFFECT OF THERMAL TREATMENT ON MECHANICAL AND DEFORMATION PROPERTIES OF STEEL REINFORCEMENT
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...

EXPERIMENTAL INVESTIGATION OF SCC WITH RECYCLED RUBBER AND RECYCLED CONCRETE AGGREGATE
The replacement of natural aggregates (NA) with alternative aggregates in concrete can contribute to the sustainable development of the construction industry. This paper aims to present research investigating the effects of recycled concrete aggregate (RCA) and crumb rubber (CR) utilization on the performance of Self-Compacting Concrete (SCC) mixtu...
