To validate criteria of JIS A 1160, experimental data for certifications and technical proofs were collected and examined by evaluation criteria specified by JIS A 1160.
The evaluation yielded the following findings: 1) All data using standard J-ring met the specification, the validity of JIS A 1160 was proved, 2) In case of using Narrow gap type J-ring, some experimental data deviated from the specification, and 3) The specification can also be applied to concrete using superplasticizer containing viscosity modifying agent.
