Abstract

In cold snowy regions, buildings are usually exposed to deicing salts. The corrosion of reinforcement steel is accelerated under the environment, and results in deterioration of concrete, especially under freeze-thaw condition. Polypropylene fibers (PPF) are used to reduce concrete cracking, and it can also improve concrete’s durability properties under freeze-thaw conditions with the existence of deicing salt. A total of four groups of specimens with different amounts of PPF were prepared. To observe the effects and roles of PPF on specimen’s durability performance, freeze-thaw tests, microscopic observation, and chloride concentration tests were carried out. The results showed that mixing PPF into specimens improved the concrete resistance of freezing and thawing with deicing salt, chloride penetration, compared to the control volume containing 0.1% PPF.
