Originální abstrakt

The article investigates the influence of mine tailing, fly ash, and mine water on strengthparameters as mine paste filling material performing the strength tests on different recipes of mortarmixes with individual types of fillers and wastewater from extraction of mine tailings. Recipe is preparedin proportions corresponding to the standard mortar and compared with a reference recipe accordingto the fresh mortar consistency test using a shaking table according to ČSN EN 1015-3. Resultingmeasured values on40×40×160mm solids samples for which the evaluation of the volume weight wascarried out in the range of 2, 7, 14, 28, 56 and 90 days according to EN 1015-10 (722400). The resultsshowed that that it is possible to prepare relatively fluid mixtures with extremely low binder dosage.And not only the water coefficient but also the granulometry of the raw material plays an importantrole in the long-term strengths of samples.
