The construction and demolition waste (CDW) could be used as backfill material to fill the voids created during the ore production in underground mining. However, there is a need to clarify the impact of CDW on groundwater pollution when it is used as backfill material in cemented paste backfill (CPB) of sulphiderich tailings (SrT). This study presents the influence of CDW on the longterm ...

Farinha et al. (2016), used kaolinite industrial waste as cement filler with 1959 cm 2 /g fineness and Amorim et al. (2003) found Blaine values for CDW fine fraction within 1170 cm 2 /g and 3400 cm 2 /g, whose results of higher fineness were attributed to waste milling process in ball mill, a missing stage in this work.
