摘要：

This research work deals with the technical viability of manufacturing new eco-efficient cement blended with thermally activated coal mining waste (ACMW). The physical-mechanical results obtained in the present work showed that the addition of ACMW (up to 20% of replacement) modified the physical and mechanical properties of the blended cement matrices. The blended cements required a great water demand, slightly accelerated settings times and revealed gain in compressive strengths at early curing times. In general terms, blended cements containing up to 20% ACMW meet the chemical, physical and mechanical requirements set out by the EN 197-1 European standard. (C) 2015 Elsevier Ltd.
