The fracture toughness of concrete is a vital parameter forstability evaluation of crack propagation, crack resistance andanti-cracking designs of hydraulic concrete structure. Hence it isnecessary to prepare a standard to specify the test methods forfracture toughness of concrete.
This Standard is prepared based on test data about concretefracture collected in the world, conducting a lot of parallel tests,referring to the fracture test standards of other countries, holdingtechnical workshop and discussions focusing on this field, andconducting calculation and theoretical analyses.
This Standard specifies the requirements of wedge splittingmethod and three-point bending beam method. When both of the testmethods are employed simultaneously and result in discrepancies,three-point bending beam method shall prevail.
Appendix D of this Standard is normative; Appendix A, B, Cand E are informative.
This Standard is proposed by China Electricity Council.
This Standard is under the jurisdiction and the explanation of theTechnical Committee of Standardization for Hydropower Construction ofElectric Power Industry.
Chief drafting organization: Hohai University.
