Abstract:
In this program, the performance of concrete masonry pavers is examined under freezing and thawing conditions of ASTM C 1262-95. The 100 x 200 x 60 mm solid rectangular pavers of eight different mixture proportions were manufactured in a commercial plant and tested to determine their physical and inherent characteristics. Mass loss and surface condition under various freezing and thawing cycles, density, absorption, compressive strength, and tensile-splitting resistance were compared in order to assess the potential of each mixture proportion as a measure of field durability and quality control. The results obtained under C 1262 also enabled comparison with the degree of severity experienced by the same group of pavers under the other ASTM and Canadian freezing and thawing (with or without deicing salt) tests.
