The research deals with the possibility of using fine recycled concrete aggregates in high performance (HPC) concrete. The main objectives include the verification of mechanical properties, the effect of shrinkage and production technology – method of water dosage. The partial goal of the research task is to verify the potential of internal curing based on the use of fine recycled concrete aggregates. The experimental program gives an account of experiments with concrete mixtures of varying content of recycled material and water. Compressive and bending strength of the concretes were measured. All samples were subjected to shrinkage measurements in time interval 1 to 28 days. The experiments evidenced that used recycled concrete aggregates affect strengths and also relative deformation of concrete.
