Laboratory Evaluation of Concrete Sealers for Vertical Highway Structures
A laboratory test method is developed to evaluate concrete liquid surface sealers for vertical highway structures and is discussed in the report. The method includes: (1) A Chloride Intrusion Screening Test wherein sets of 10 concrete prisms per sealer are partially immersed in salt brine; (2) A Water Absorption-Water Vapor Transmission Test; and (3) A Freeze-Thaw Resistance Test as per ASTM C-666, Procedure A, with concrete durability measured by the resonant frequency technique. The findings of the study indicate that: (1) The Chloride Content vs. Time relationship for coated concrete is non-linear and sealer-dependent; (2) The resonant frequency test is the only reliable method of measuring the durability of coated concrete under freeze-thaw cycling. Rhode Island concrete sealer specifications are revised to incorporate the results of the present study.
