PERFORMANCE-ENHANCING PARTICULATE PREMIX COMPRISED OF MINERAL FINES TREATED WITH ONE OR MORE ADDITIVES
Performance-enhancing particulate premixes contain mineral fines treated with one or more performance-enhancing additives. Also disclosed are methods of manufacturing performance-enhancing particulate premixes and cementitious compositions that incorporate such performance-enhancing particulate premixes, a hydraulic cement binder, and optionally one or more supplementary cementitious materials (SCMs). The cementitious compositions can be dry cementitious compositions, fresh cementitious compositions (e.g., mixed with water to form a shapable mix), and hardened cementitious compositions (e.g., that contained hydrated cement). The performance-enhancing particulate premix can be formulated and manufactured to offset an increase in water demand and increase flow when used to replace a portion of Portland cement in concrete. For example, mineral fines are treated to yield performance-enhancing particulate premixes comprising one or more types of mineral fines and one or more types of water reducers.
