Dependence of the hydration rate of Portland cement on particle size distribution

抄録

An equation for the hydration reaction developed by Tomozawa, which was originally applied to a single particle, was applied to the hydration process of Portland cement with a known particle size distribution. We also studied the theoretical change of porosity after hydration as affected by the water-to-cement ratio by using an equation of hydration that considers the particle size distribution. Consequently, we derived a correlation between the porosity and the reaction rate, which was in agreement with the experimental values.
