 Abstract
In this study, the coefficient of permeability for cement mixtures including the powdered sludge of basalt, sand or fly ash with different mixed ratios was measured in order to reuse the powdered sludge of basalt in Jeju Island as the cut off materials. As the permeability test results, the coefficient of permeability for the cement mixtures with fly ash was increased with increasing the fly ash contents. The amount of fly ash in the cement mixtures should be mixed with less than 8 %. Meanwhile, the coefficient of permeability for the cement mixtures with sand was increased with increasing the sand contents. The amount of sand in the cement mixtures should be mixed with less than 40 %. According to the comparison result of cement mixtures including fly ash or sand, it is more advantageous to put the sand into the cement mixtures, rather than mixing the fly ash.
