What is 28-Day Concrete Cylinder Test Results about?
The document summarizes a compression test report for 28-day concrete cylinders cast on 02/03/18. Testing on 30/03/18 showed the cylinders for footings F5 and F8 had an average compressive strength of 2007 psi (67%), below the required 3000 psi. The 7-day and 14-day strengths were satisfactory, so the low 28-day strength was likely due to an error in casting the cylinders or excess water in the transit mixer sample.
