Preparation of High-Performance Concrete for Adjusting of Possibility of its Usage in Building Practice

Technology of High-Performance Concrete (HPC) presents one of advanced concrete technologies. In comparison to common concrete, HPC is characterized by much better qualitative parameters both for fresh and hardened concrete. However, utilization of adequate materials as well as specific processes of both the production and handling of fresh concrete is required to achieve the above standard parameters of concrete. Currently, limited possibility of utilization of local source materials with applicable parameters curtails wider production of HPC within the building practice. Results of experimental approval of HPC properties which was prepared from local aggregates are presented in the paper. Used aggregates have not appropriate parameters for application into HPC on its face. Therefore the achieved results show the potential of its applied utilization.
