Compressive strength test results are crucial for concrete producers to uphold quality control, assess product performance, comply with standards, optimize mix designs and ensure customer satisfaction.
Sharing test results is required as per CSA A23.2-25C Section 6 Reporting which states that, unless otherwise agreed, test results shall be provided to the concrete supplier within five working days of completion of the test. Both field and laboratory test reports shall include all information required by the applicable test methods of CSA A23.2. The Association cannot stress this clause enough, as it allows the concrete producer to evaluate the performance of their raw materials in real time and allows them to make mix design adjustments to guarantee satisfactory concrete performance. Keeping the concrete producer up to date with the latest results allows them to identify trends and take proactive measures to ensure product consistency, performance and sustainability.
It is therefore critical that all tests results are shared with the concrete producer whenever concrete is tested onsite. Testing data should be made available to the concrete supplier as soon as possible to allow them to evaluate the overall performance of the concrete and take corrective action if necessary.
