Study on Hydration Degree of Portland Cement-Slag Complex Binders

Liu, Reng-Guang / Yan, Pei-Yu

The hydration degree of Portland cement-slag complex binders was investigated by hydration heat, chemically bound water amount, EDTA selective dissolution and mortar compressive strength. Different hydration degree of complex binders was obtained with different methods. Hydration heat and EDTA method indicated that reaction degree of slag was much lower than cement and the total reaction degree of complex binders was also lower than neat cement. However, chemically bound water amount and mortar compressive strengths of complex binders blended with slag within certain limit were higher than neat cement at late age.
