Description	High performance concrete (HPC) with natural zeolite and ceramic powder as Portland cement replacement in the amount of up to 40% is analyzed in the paper. Natural zeolite and ceramic powder belong to the pozzolanic materials. Utilization of pozzolanic materials is accompanied with lower demand on energy needed for Portland clinker calcination which usually results in lower production costs and lower CO2 emis-sions. Besides, the application of pozzolanic materials can improve properties of hardened concrete, namely strength and durability-related parameters. Basic physical characteristics, hygric properties and thermal prop-erties are studied and compared with reference concrete. The effective amount of pozzolanic materials used as a partial replacement of cement for concrete production is found. Measurement results show that natural zeolite and ceramic powder have a potential to replace a part of Portland cement in concrete in building industry. It is shown that although from both environmental and economical points of view it would be desirable to use its highest possible amounts in concrete production, the extent of Portland cement replacement which could be chosen in preparation of concrete mixes has relatively strict limitations.
