Can microfibres prevent frost damage?
To analyze the influence of microfibers on the durability of frost susceptible cementitious systems, eight paste mixtures and eight mortars were batched under vacuum. Such a procedure was found to reduce very significantly the volume of air entrapped in the micro-reinforced pastes and mortars during the mixing process. The test parameters included the water/binder ratio (0.35 and 0.45) and the fiber type and dosage. The pastes were made with 2 % steel fibers, 5 % steel fibers and 2 % carbon fibers. The mortars were made with 1 % steel fibers, 2 % steel fibers and 1 % carbon fibers. The results of the freezing and thawing cycle tests and of the deicer salt scaling tests show that the micro-fibers reduce the rate of deterioration due to freezing phenomena but do not completely prevent damage.
