Abstract

This study examined the effects of particle size on characteristics of cement by controlling the particle size of commercial cement. Through a size adjustment, the cement has increasing more of particles that are less than $10{\mu}m$ in size so the initial reaction time has been shortened as a result of improvement in the early hydration reaction. Additionally, it showed a great characteristics of strength from the early age and the initial hydration heat has been increased as well. In the upper and middle parts cements, the initial hydration reaction rate contribution is high with the $10{\mu}m$ compared to original cement. So the initial hydration reaction rate is improved and as a result, it also showed relatively high hydration heat as well. Additionally, adiabatic temperature also showed an increase rate in the results.
