Abstract

Hydraulic properties of CA2-based clinker synthesized by Hydration-Burning Method was studied by calorimetry, analysis of suspension, thermogravimetry, scanning electron microscopy and X-ray diffractometry. Hydraulic properties of the clinker was so activated that heat of hydration of the clinker evolved faster than that of CA synthesized by conventional method. In suspension of W/C=33, dissolution of the clinker began at nearly same time as that of CA, but precipitation of AH3 and rise of [OH-] occurred fairly faster in the suspension of the clinker than that of CA. From the beginning of hydration, AH3 was produced and became a main phase of the hydrate with minor phase of CAH10 and C2AH8, but C3AH6 was not produced at ambient temperature.
