Re: Concrete Test Reports
Dear Customer,
The Standard Specification for Ready-Mixed Concrete,
ASTM designation C 94, includes the following stipulation.
,,When the strength of concrete is used as a basis for
acceptance, the manufacturer shall be entitled to copies of
all test reports."
Please be sure we are added to the mailing list for
copies of concrete test reports. The reports should be sent
to my attention.
Thank You,
