acceptance testing of concrete in accordance with Section 1905.6.2 and strength test acceptance criteria shall comply with the provisions of ACI 318, Section 5.6.3.

Comparison of Strength and Construction Tolerances in Concrete

Two approaches to the tolerance limit for compressive strength of concrete in reinforced members are compared. One tolerance limit for strength, in use since 1971, is f c500 psi (3.4 MPa). Another tolerance, based on 0.90 f c, provides a more direct link between design and quality control criteria, consistent with the use of strength reduction factors.

How to Evaluate Concrete Tests per ACI 318 Structural

1. With the lower f'c derived from the strength tests above, the structural engineer should review the design of the affected portion of the structure to determine if the lower f'c is acceptable. If the lower f'c is acceptable, then no further efforts are required and the concrete can be accepted. Steps still should be taken by the contractor to increase the compressive strength of the concrete for future mixes. 2.
