Partial replacement of cement with granular marble residue: effects on the properties of cement pastes and reduction of CO 2 emission

摘要: The effects of CP V Portland cement replacement with granular marble residues were investigated. physical–chemical properties the starting materials and pastes characterized by XRD, XRF, TG/DTA, SEM granulometric analyses. Axial compressive strength, apparent density, capillary total capacity water absorption hardened 0, 10, 20 30% replacements, aged for 28 days, characterized. results indicated that partial residue did not affect hydration but provided packaging improvements some filler action. reduction CO2 emission was estimated as 0.28 million tons per year due to 10% residue. this is an alternative means reduce emissions in industry reuse otherwise could be inadequately disposed.
