Critical Chloride Corrosion Threshold for Galvanized Reinforcing Bars
(University of Kansas Center for Research, Inc., 2007-12)Galvanized reinforcement is evaluated to determine the chloride content required for corrosion initiation. The bars conform to ASTM A 767, except that no chromate treatment was applied. Specimens containing the galvanized ... -
Effects of Deicers on Concrete Deterioration
(University of Kansas Center for Research, Inc., 2007-12)Concrete specimens were exposed to weekly cycles of wetting and drying in distilled water and in solutions of sodium chloride, calcium chloride, magnesium chloride, and calcium magnesium acetate with either a 6.04 molal ... -
Development of a Wireless Real-Time Productivity Measurement System for Rapid Bridge Replacement
(University of Kansas Center for Research, Inc., 2008-01)Increased attention has been paid to rapid bridge replacement, one of the critical components of the nation’s transportation network, since the terrorist attacks on September 11, 2001. To enhance the capability of rapid ... -
Fatigue Behavior of Welded Connections Enhanced with UIT and Bolting
(University of Kansas Center for Research, Inc., 2008-03)A common problem in bridges employing welded steel girders is development of fatigue cracks at the ends of girder coverplates. Fatigue cracks tend to form at the toes of the transverse welds connecting a coverplate to a ... -
