Sažetak
This study investigated the pozzolanic activity of natural zeolite tuff from Donje Jesenje (Croatia) site and waste construction brick as a replacements for Portland cement according to HRN EN 196-5. The chemical composition of Portland cement type CEM I, zeolite tuff and waste construction brick was determined by EDXRF device. Pozzolanic activity examinated on cement samples with the addition of zeolite tuff and waste brick in the amount of 20 and 30 wt. %. Samples were kept 8 days in water bath at 40 °C. Determination of total alkalinity, and the concentration of CaO in an aqueous solution above the solid samples, confirmed the pozzolanic activity of the samples since the experimental points are located below the saturation curve in the diagram of isothermal solubility of calcium hydroxide. Results confirmed the possibility of applying the pozzolanic activity tests in determining of optimal content of pozzolanic material in cement which is especially important for pozzolanic cement industry.
