Abstract

Cement-SCM compositions have improved strength compared to cement-SCM compositions made using conventional blended cements and methods. The cement-SCM compositions may contain: (A) a fine interground particulate component with (1) a hydraulic cement fraction and (2) a supplementary cementitious material (SCM) fraction; (B) a coarse particulate component comprised of coarse SCM particles not interground with the fine interground particulate component; and optionally (C) an auxiliary particulate component not interground with the fine interground particulate component or the coarse particulate component. A method of manufacturing a cement-SCM composition may be performed by: (A) intergrinding hydraulic cement (e.g., cement clinker) with one or more SCMs to form a fine interground particulate component; (B) blending, without intergrinding, the fine interground particulate component with a coarse particulate component comprised of coarse SCM particles; and optionally (C) further combining, without intergrinding, an auxiliary particulate component with the fine interground particulate component and the coarse particulate component.
