Hydration properties of calcium sulfoaluminate-Portland cement blends

Bianchi, M. / Canonico, F. / Capelli, L. / Pace, M.L. / Telesca, A. / Valenti, G.L.

The X-ray diffraction analysis and mercury intrusion porosimetry were employed to investigate the hydration process of calcium sulfoaluminate-(CSA)-Portland cement blends with (4CaO)(3Al2O3)(SO3) mass concentration, (3CaO)(SiO2)/(4CaO)(3Al2O3)(SO3), and CaSO4/(4CaO)(3Al2O3)(SO3) mass ratios ranging from 7.7 % to 22.0 %, 1.0 to 6.5, and 0.5 to 1.2, respectively. Owing to the hydration of adequate (4CaO)(3Al2O3)(SO3) contents and the generation of sufficient quantities of expansive ettringite, blends with (4CaO)(3Al2O3)(SO3) amounts as well as (3CaO)(SiO2)/(4CaO)(3Al2O3)(SO3) and CaSO4/(4CaO)(3Al2O3)(SO3) values comprised between 17.6 % and 22.0 %, 1.0 and 1.7,0.5 and 1.0, respectively, showed high-early strengths and low drying-shrinkage when compared to normal portland cements. The formation of expansive ettringite was associated with concentrated pore distributions and most preferred pore radii ranging from either 47 nm to 225 nm or 367 nm to 896 nm, depending on both (3CaO)(SiO2)/(4CaO)(3Al2O3)(SO3) and CaSO4/(4CaO)(3Al2O3)(SO3) ratios.
