The Mechanical Properties of Fine Recycled Aggregate Concrete after Freeze – Thaw Cycles

Popis výsledku v původním jazyce

This paper is focused on mechanical properties of fine recycled aggregate (FRA) concrete after freeze – thaw cycles. The use of FRA is connected with uncertainties and doubts. The most unknown aspects of FRA concrete are related to durability. This paper presents results of mechanical properties of concrete containing FRA after freeze – thaw cycles. The FRA from concrete waste originated from recycling plant in the Czech Republic was used in experiments. Four concrete mixtures were analyzed in total. The first, concrete mixture with natural sand, cement and water was prepared as a reference concrete mixture. In other mixtures, natural sand was replaced by FRA in various replacement ratios, specifically 10%, 20% and 30%. All concrete mixtures were designed with the same parameters for clear comparison. As a consequence of the quality and amount of FRA, the test results showed the influence of FRA to the freeze – thaw resistance of concrete.
