Milling parameters and solid waste characterisation to use as supplementary cementitious materials

Abstract Despitethe increasing number of publications on residual raw materials as supplementary cementitious (SCM), the milling beneficiation process and its parameters have been underexplored presented. In this context, study aims to evaluate for marble, clay tile, brick, phosphogypsum waste processing recycling SCM. The were benefitted by grinding, sieving, in a planetary ball mill, varying time rotation speed parameters. was characterised helium gas pycnometry, DSC, BET specific surface area, XRF, TGA, XRD/Rietveld. Waste which mineral composition phases formed at higher temperatures associated with demands energy lower grindability indexes. Marble (MW) has similar commercial limestone (PG) can be an alternative natural gypsum materials. Clay brick (CBW) tile (CTW) potential used SCM replace calcined clays, although CTW requires during processes.
