DIRECT TENSILE TESTING METHOD OF CEMENTITIOUS CURED BODY

摘要

PROBLEM TO BE SOLVED: To provide a direct tensile testing method of a cementitious cured body capable of being simply carried out even at a construction site or the like of a concrete structure without requiring a large-sized testing machine.;SOLUTION: In the direct tensile testing method of the cementitious cured body for measuring the tensile strength of a test piece 1 by bonding and fixing the lower part of the test piece 1 to the cured body 2 with a compression strength of ≥5 N/mm² and pulling the upper surface of the test piece by a tensile tester 3 to break the same, a building study type adhesive strength tester can be used as the tensile tester. The adhesion and fixing of the lower part of the test piece with the cured body with a compression strength of ≥5 N/mm² is preferably performed by casting mortar or concrete in a predetermined form so as to expose the upper part of the test piece after the test piece is installed in the form and curing the same. As mortar or concrete, it is preferable to use fast-setting mortar or concrete developing a compression strength of ≥10 N/mm² per one material life day.;COPYRIGHT: (C)2005,JPO&NCIPI
