  • Abstract:
    Materials related distress (MRD) characterized by “starburst” type corner spalling at the longitudinal centerline joint, and occasional transverse joint spalling have developed at a rapid rate in a number of JPCP projects constructed since 1999. The main objective for this project was to isolate the major cause(s) for suspected freeze-thaw deterioration, and to provide recommendations for improved materials specifications in order to ensure long-term freeze-thaw resistance to severe surface exposure conditions (i.e. surface contact with either water or 3% NaCl) during repeated freezing and thawing. Four younger (<10 years) field projects with this type of MRD and four older field projects without MRD were selected for laboratory freeze-thaw testing for two different exposure conditions (water and 3% NaCl) during cyclic freeze-thaw. Rapid surface deterioration developed due to deicer salt exposure within a few freeze-thaw cycles for the concrete with MRD problems. The concrete without MRD had significantly improved deicer scaling resistance. Microscopic examination of the scaled surfaces demonstrated that excessive expansion and cracking had developed within the Portland cement paste consistent with inadequate air-void system. ASTM C457 test method was used to evaluate the air-void system in the hardened concrete. The four concrete projects which had not developed freeze-thaw problems at the joints also had higher air contents (>5.5%) while the concretes with low air had severe deterioration. A substantial improvement in deicer scaling resistance was obtained for MDOT’s low-cement concrete containing slag cement (328 lbs Type I, and 162 lbs slag cement). The improvement was attributed to a better quality paste-coarse aggregate interface (i.e. without air-void clustering) and air-void system (smaller sized bubbles), and lower paste permeability (i.e. lower water uptake rate).
