✦ Synopsis
Specimens of 0,25 water-cement ratio concrete with various air void spacing factors were tested for freezethaw durability in accordance with ASTM Standard C 666 (procedure A) and for deicer salt scaling resistance in accordance with ASTM Standard C 672. All specimens were moist cured 14 days. Few specimens showed signs of deterioration after 300 and 800 cycles of freezing and thawing and a critical air void spacing factor of approximately 750 ~m was determined.
All specimens that underwent scaling tests showed a very good resistance to deicer salts and, even after 150 cycles, a maximum of only 0.6 kg/m 2 of scaled off particles was measured.
