    Grout 28day break vs 7day met spec

    Thank you guys for your feedback. My decision was to have the 28 day breaks. And, as I said numerous times nobody is concerned until a nonconformance is evident. Thanks,

    Why test the 28 day grout when 7day passed?

    Client ordered 3000 psi Grout. Project requires 2000 psi. Contractor wants to know if we still have to break the 28 day break eventhough at 7 days exceeds the 2000 psi spec. What are the unseen potentials with not breaking the 28 day grout samples?
