DESIGN AND EVALUATION OF HIGH STRENGTH CONCRETE FOR GIRDERS
High strength concrete was required for the construction of of the Westbank Expressway. This project was initiated to determine if the required strength could be obtained in a production mode. Scope of this project included laboratory mixing, testing and field evaluation. The prime conclusion reached on this study was that high strength concrete (minimum compressive strength 6500 psi) can be obtained. The results of this study indicated that both limestone (ASTM #7 gradation) and regular Class A concrete produced the necessary strength, however, limestone is considered to be the best material to achieve high strength. A set of changes in the Class P(M) specifications in the form of special provisions to the construction project were written to be used by the consulting engineers for their presentation to the Department for their review and approval.
