摘要 This article studies the frost resistance of polyvinyl alcohol (PVA) fiber reinforced cementitious composites. The test samples contain different PVA fiber volume fractions such as 0, 0.5%, 1% and 2%. The freeze-thaw test is carried on in TDR type apparatus. The outward appearance, the weight loss factor and the relative dynamic elastic modulus are analyzed, and conclusions are drawn that PVA fibers can significantly improve the frost resistance of cementitious composites and frost resistance of PVA fiber reinforced cementitious composites with fiber volumetric fraction of 1% is better.
