HIGH-PERFORMANCE CONCRETE WITH RECYCLED CONCRETE AGGREGATES: EFFECTS OF PRODUCTION TECHNOLOGY ON MECHANICAL PROPERTIES AND SHRINKAGE

Popis výsledku v původním jazyce

This research project explores the potential of incorporating fine recycled concrete aggregates (RCA) into high-performance concrete (HPC). The primary objective of this study is to assess the mechanical properties, shrinkage behaviour, and production methodologies, with a particular emphasis on the approach to water dosing. A secondary objective is to assess the potential of internal curing using RCA. The experimental program encompasses concrete mixtures with varying proportions of recycled material and water content. The compressive and bending strength values of the samples were measured, and all samples were monitored for shrinkage over a period of 1 - 28 days. Contrary to the prevailing assumption that the replacement of natural aggregates with recycled ones results in a reduction in strength, this study proposes an alternative conclusion. Specifically, the study indicates that mixtures containing 15% natural aggregate, when substituted with RCA, demonstrate higher strength than those composed exclusively of natural aggregates.
