Cement concrete pavement slabs used in highway construction are planer structures.

Apart from regular factors considered in analysis of concrete pavements, temperature effects influence the slab size, joint spacing and temperature reinforcement design.

These materials result in concrete properties that could be different from those of conventional concrete. (17.8-mm) Diameter Strands in Pretensioned Concrete Bridge Girders Testing and Predicting the Modulus of Elasticity of Concrete This material is based upon work supported by the Federal Highway Administration under Cooperative Agreement No. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the Author(s) and do not necessarily reflect the view of the Federal Highway Administration.

Three girders from one production line of five girders were selected for evaluation.

Two of the girders were cast with SCC and one with conventional concrete as the control.

The SCC created a smooth surface to the girders without signs of bleeding or discoloration. "Shear Behavior of Reduced Modulus Prestressed High-Strength Self Consolidating Concrete Members Subjected to Elevated Concrete Fiber Stresses," PCI National Bridge Conference, 2009.

On the other hand, the moisture content of the aggregate and variations in aggregate gradations have a greater impact on the properties of SCC than for conventional concrete. Further Information For further information about this article, contact the author at [email protected] or 360-705-7181.
