METHOD FOR MEASURING ACTIVITY OF UNCURED STATE CEMENT COMPOSITION, AND REUSE SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for readily and quantitatively measuring the activity of cement contained in an uncured state cement composition, and to provide a method for reusing cement, on the basis of results of the measurements.

SOLUTION: The uncured cement state composition is determined by a measuring means, based on electric conductivity, and this enables appropriate correction of the blending of cement composition materials to be newly kneaded, on the basis of the determination and reuse of cement.
