Abstract	The early stage of Portland cement hydration was studied using cold field emission scanning electron microscopy and isothermal conduction calorimetry. Particular attention was focused on samples from the end of the induction period, where an additional peak in the tricalcium silicate hydration reaction has recently been discovered. High-resolution images were obtained that enabled observation of features on the 5 nanometer scale.The research also examined the effects of cement grinding and additions of tricalcium aluminate and tetracalcium aluminoferrite at the end of the induction period.
