Abstract
Non-hydraulically reactive blended particulate compositions for use in making low carbon blended cement or low carbon concrete include a pozzolanic component having a first D90 and a mineral filler component having a second D90 greater than the first D90 dry blended without intergrinding, wherein the composition is free of hydraulic cement. The pozzolanic component can have a D90 less about 45 μm and the mineral filler can have a D90 greater than about 45 μm. The pozzolanic material can be fly ash, bottom ash, steel slag, silica fume, metakaolin, volcanic ash, natural pozzolan, calcined shale, calcined clay, and/or ground glass. The mineral filler component can be aggregate fines, quarry fines, limestone powder, granite fines, stone dust, rock dust, marble dust, mine tailings, pulverized bottom ash, pulverized metallurgical slag, ground recycled concrete, pulverized shale from shale oil extraction, or pulverized sand from tar sand extraction.
