Sažetak
This work was performed by leaching samples of Portland cement with various additions of waste zeolite and mud according to leaching test EN 12457. Samples were hydrated 28 days at a temperature of 20 oC. The success of the stabilisation and solidification was studied by determination of zinc in the solid samples and solutions, after leaching with EDXRF device. The concentration of zinc ions in solutions and solid samples depends on the addition of waste zeolite and mud and leaching time. According to the European leaching test EN 12457 acceptable shares of waste material are those when the concentration of zinc in the solution does not exceed regulatory limit. The results show that it is possible to use the additions up to 10 wt. %.
