Water damage evaluation of concrete infrastructure.

摘要

This study presents an experimental program to evaluate the effect of a special waterproofing material, International Chem-Crete Pavix (CCP), on the durability of concrete. The experimental program identified the concrete mix design commonly used for pavement and other infrastructure as set by Texas Department of Transportation (TXDOT). The tests conducted include the water absorption and air void (ASTM C 642), freeze-thaw (ASTM C 666), chloride penetration (ASTM C 1202), and petrographic (ASTM C 457) test. The tests were performed on both cored and laboratory treated and untreated specimens.; The absorption test was performed on the concrete specimens with water cement ratio of either 0.35 or 0.5. The results of this test include percent absorption, specific gravity, and percent permeable void in the concrete. For freeze-thaw test, the optional length change test was performed. The test was performed for 300 freeze-thaw cycles. Measurement including length and weight were obtained for approximately every 50 cycles. (Abstract shortened by UMI.)
