Abstract:
Paper presents the results of an experimental investigation on the freeze-thaw durability of polymer modified concrete (PMC). Basically, prism specimens were subjected to a maximum of 900 cycles of freezing and thawing, using ASTM C 666 Procedure A. Five sets of specimens with various amounts of polymer content were tested. The polymer consisted of a liquid epoxy resin and a curing agent (or hardener). Weight and fundamental transverse frequency were measured at various intervals of freeze-thaw cyclic loading. The results indicate that the freeze-thaw durability of PMC is better than that of non-air-entrained plain concrete. The PMC with polymer-cement ratio of 0.4 or higher can withstand 900 cycles of freezing and thawing.
