=m« CRMCA Concrete Quality Pre-Construction Checklist Contact Information for Test Results to be sent to (via email, fax, mail) to Owner: Architect: Structural Engineer: Concrete Supplier: General Contractor: Other: Acceptance of Concrete Strength in accordance with ACI 301-10 The strength of standard molded and cured strength specimens is satisfactory if the following criteria are met: 1.6.6.1 a Every average of three consecutive strength tests equals or exceeds the specified compressive strength fc. 1.6.6.1 b No strength test result falls below fc by more than 500 psi when fc is 5000 psi or less, or by more than 0.10 fc when fc is more than 5000 psi. Coring Section 1.6.6.2-The strength of concrete in the area represented by cores,tested in accordance with ASTM C42, is considered adequate when the average compressive strength of the cores is at least 85%of fc and if no single core is less than 75%of fc. Statement of Acknowledgement The American Concrete Institute (ACI) and the ASTM International have established many standards and practices related to the performance and safety of concrete construction. The quality of concrete construction is heavily dependent upon the commitment of the project team to the standard practices associated with the production, delivery, placement, and testing of ready mixed concrete.
