Abstract: In the investigations synthetic zeolite - hydrosodalite (Na6+x(SiAlO4)6(OH)x·nH2O), modified hydrosodalite ferro silicon production waste - SiO2 fume was used. It was found changes in the strength of hardened cement paste, density and water penetration properties. Investigations are used by preparing samples with 2%, 5%, 10% and 15% pozzolanic additives from the weight of the cement. It was also found the influence of additives on the hydration temperature. In the investigated conditions the maximum compressive strength of samples with 10% of the modified hydrosodalite additive after 28 days had, compressive strength increased to 101 MPa. By using 5% SiO2 fume penetration of cement stone reduced to 8.41%
