Title: FREEZE-THAW STUDIES ON CONCRETE STRUCTURAL ELEMENTS
Accession Number: 00637820
Record Type: Component
Availability: Find a library where document is available Abstract: The effect of freeze-thaw cycles on plain concrete decks and concrete-filled steel grid decks is presented. The test program simulates field temperature conditions. An attempt has been made to correlate the freeze-thaw effect to the longitudinal growth behavior of concrete-filled steel grid decking systems. To study the longitudinal growth, emphasis has been placed on the determination of expansion and contraction coefficients of concrete for different temperature ranges. Residual tensile strain buildup, a result of the differential expansion and contraction coefficient of concrete, is found to be a function of freeze-thaw cycles. Thermal incompatibility between concrete and steel and the consequent growth in concrete-filled steel grid decks are dealt with from the viewpoint of thermal creep.
