Abstract:Concrete mix designs and components may currently be changed during the course of a project. The possible negative effects of such changes on concrete strength, are not determined under the current plant control/project control process. Also, the current La. DOTD specification for acceptance of concrete is based on 28 day compressive strength, but design is based on 28 day flexural strength. This study proposed to develop an early strength test would allow concrete to be tested within 24 hours to identify potentially inferior concrete prior to placement of large quantities and to evaluate 28 day flexural strength of Louisiana concrete.
