Abstract |
In this study, the mixing characteristics and 28-day compressive strength of ready-mixed concrete delivered to a construction site were evaluated before and after the implementation of a quality inspection standard for unit water content. Our dataset comprised 61 mix designs and 594 compressive strength test results. The compressive strength of concrete specimens, cast during site acceptance testing of the ready-mixed concrete, was assessed. The results indicated a reliable correlation between unit water content and compressive strength after the application of the unit water content quality inspection standard.
