METHOD FOR DETERMINING STRENGTH OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a simple decision method for specifying the strength range of concrete structure. SOLUTION: In the decision method for specifying the strength range of a concrete structure, a concrete core is sampled from a concrete structure and relative hardness at a micro part of cement paste is measured from the top surface of the concrete core toward a deep part. Strength range of the concrete structure is specified from the top surface of the concrete core to a deep part by processing the measurements statistically.
