Analysis of the Rate Constant for Hydration Kinetics of the Cement and Ash Fly in the Solidified Residues System Based on the Measurement of Ca(OH)2

Based on the hydration kinetics of the cement matrix material, the paper presents a chemical analysis method by means of analyzing the contents of Ca(OH)2 in cement matrix material. The kinetics constant for the cement, ash fly in the residues system solidified by recycled cement, ash fly was determined at different temperature. The hydration kinetics characteristic of the residues system after being hydrated 7 days is first order reaction.
