Two-stage concrete made with single, binary and ternary binders
The mechanical properties of two-stage concrete (TSC) made with various grout mixtures and incorporating single, binary, and ternary binders were investigated in the present study. Different supplementary cementitious materials, including class F fly ash, silica fume and metakaolin were added as partial replacement for ordinary Portland cement. Mechanical properties of TSC including compressive and tensile strength and modulus of elasticity at 7, 28, and 56 days were evaluated. Results show that the binder composition has a great influence on the fresh and hardened properties of the grout used in TSC and consequently on TSC’s mechanical properties. Moreover, empirical relationships between the properties of the grout and those of the corresponding TSC were proposed, offering a potential tool for estimating TSC properties based on primary grout properties.
