ACI 311.6M-09 PDF Download

The ACI 311.6M-09 standard outlines the minimum requirements for testing ready mixed concrete at the project site. The objective of this standard is to ensure that the concrete meets the specified field-measured properties and laboratory-measured compressive strength for acceptance at the site.

The standard covers various aspects of testing, including the making and curing of test specimens, conducting field and laboratory tests, and the qualification of personnel and laboratories involved in performing these tests. It emphasizes the need for an independent Testing Agency to carry out the required testing services, ensuring that there are no conflicts of interest that could impact the objective reporting of the test results.

However, it is important to note that this standard does not apply to the testing requirements and responsibilities of the construction contractor. It primarily focuses on the specific testing services that should be completed by the Testing Agency engaged by the Owner of the project. The standard aims to provide a standardized approach to the testing of ready mixed concrete to ensure its quality and suitability for use in construction projects.
