Abstract: The compressive strength of mortar, the pore structure, hydration heat, non-evaporable water content of composite binder containing slag, which may be used to prepare self-consolidating concrete, were investigated. The binder paste was cured at different temperature to simulate the condition of real concrete structure. The binder containing 30% of slag possesses almost same characteristics as pure Portland cement. The binder containing 70% of slag shows much lower properties than them. The dosage of slag in composite binder should be controlled in a reasonable range. Elevated temperature can excites the hydration of binders but shortens the hydration continuing time, which results a coarse paste microstructure and a low final strength.
