Mass concrete cold joints standard

[tbocgu]

I'm interested in standards to evaluate the acceptance of cold joints in masive concrete, poured to support a turbine-compressor, or similar literature or methods to evaluate the existance of a cold joint in this type of structure.

The case is that when the forming was removed there was apparently a cold joint in the structure, i'm not sure because the lap of time between one poured and another was less than one Our.

I dont have standards references.
Possible evaluation might include coring of the joint zone.
Remediation may be done by pressure grouting in alternate zones along the joint.
