Durability of Ternary Cements Based on New Supplementary Cementitious Materials from Industrial Waste

Cement-based materials decay with exposure to aggressive agents, a development that raises infrastructure operation and maintenance costs substantially. This paper analyses the inclusion of ultrafine construction demolition (UC&DW) biomass-fuelled power plant (BA) waste as pozzolanic additions cement in pursuit more sustainable eco-respectful binders assesses durability end when exposed seawater, chlorides (0.5 M NaCl) or sulphates (0.3 Na2SO4). The effect adding silica fume (SF) at replacement ratio 5% was also analysed. Durability determined using methodology proposed by Koch Steinegger, whilst microstructural changes were monitored mercury intrusion porosimetry (MIP), X-ray diffraction (XRD) scanning electron microscopy (SEM) for fuller understanding processes. According findings, new blended cements containing 20%UC&DW + 10%BA 20%BA 5%SF resist attack media studied, 56-d corrosion index over 0.7. composition reaction products generated is essentially same OPC SCM-bearing materials. results show optimal SCM 30%.
