The effect of high volumes of two supplementary cementitious materials (SCMs) (fly ash and slag) on the mechanical performance of self-consolidating concrete (SCC) was investigated. Binary and ternary mixes were prepared replacing 60–90% of the Portland cement in the control mix (cement = 415.1 kg/m3). Mix designs were selected such that a wide range of CaO/(SiO2 + Al2O3) was achieved. Results show that SCC containing high volumes of SCMs have similar engineering properties (compressive strength, elastic modulus, creep, shrinkage) as conventional SCC at later ages (⩾28 day). A novel efficiency expression was developed to predict compressive strength.
