文摘

Ten concrete mixtures with high content of fly ash were prepared and tested. Basic physical and mechanical properties of HVFAC were tested. Determination of radionuclide content in HVFAC and its all solid components was done. Gamma spectrometry and radon exhalation with accumulation techniques were used. Radiological analysis of all investigated materials was carried out by means of I-index.
