A kinetic study of delayed ettringite formation in hydrated Portland cement paste
Results of a kinetic study of delayed ettringite formation in hydrated cement paste by XRD analysis over the temperature range 5 to 85 deg C are reported. Two competitive reactions in terms of gypsum consumption are discussed. These involve both CaO-SiO2-H2O gel and the hydrated calcium aluminates. An increase in temperature apparently accelerate sulphate absorption rate by CaO-SiO2-H2O gel. Ettringite formation is relatively temperature independent during the first day of hydration in the range 65 to 85 deg C. A mechanism for secondary ettringite formation in high temperature steam cured Portland cement material is advanced.
