Originální abstrakt

The aim of this work was to investigate the effect of addition of elements present in secondary raw materials on the hydration and compressive strength of Portland cement. Ordinary Portland cement (OPC) has been used to solidify hazardous waste for about 25 years and the effect of waste components on the hydraulic activity is an interesting object for the research. In this study Zn nitrate, chloride and oxide were added to Portland cement. The concentrations of 0.1 and 1.0 weight percent of zinc in cement were tested. After 1, 7 and 28 days the compressive strength was reduced or similar by the addition of zinc in comparison with pure cement. This difference is probably due to a delay in tricalcium silicate hydration as shown by isothermal calorimetry.
