Carbonated Wollastonite and Municipal Solid Waste Incinerations (MSWI) As Supplementary Cementitious Materials

Supplementary Cementitious Materials (SCMs) usage in concrete have been studied in relation to its benefits on the compositional properties on concrete. As the cement industry increases its emissions of CO2, the pressure to find SCM sources increases and the dependence of ordinary Portland cement (OPC) decreases. As the cement industry pursues to find ways reduce carbon dioxide emissions, multiple studies have been conducted on alternative SCMs to show their effect on reducing CO2 emissions and other compositional properties (such as strength). In this study, we studied the effects of municipal solid waste incinerations (MSWI) and wollastonite in their potential for reducing carbon emissions. We assessed MSWI and wollastonite for sequestering CO2 and evaluated the effects of carbonated wollastonite and MSWI on the cementitious matrix.
