MEASURING METHOD OF CRACK OCCURRENCE STRENGTH OF ULTRA-HIGH STRENGTH FIBER REINFORCEMENT CONCRETE, AND SPECIMEN OF ULTRA-HIGH STRENGTH FIBER REINFORCEMENT CONCRETE USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method or the like of accurately and efficiently measuring a crack occurrence strength of an ultra-high strength fiber reinforcement concrete.SOLUTION: A measuring method of a crack occurrence strength of an ultra-high strength fiber reinforcement concrete of the present invention includes: using a cylinder specimen having undergone (A) a polishing process of the cylinder specimen, (B) a selecting process of a measuring object, (C) a pasting process of a strain gauge, and (D) a mounting process of the cylinder specimen; determining the relationship between a load and a strain; and determining and measuring, as the crack occurrence strength, a tensile stress corresponding to the load at a point at which the linear elasticity is failed in the relationship between the load and the strain.SELECTED DRAWING: None
