EFFECT OF PVA FIBER ON THE FREEZING AND THAWING BEHAVIOR OF CONCRETE

摘要：

　　In this study,the effect of polyvinyl alcohol (PVA) fiber on the concrete damage under freeze-thaw condition was investigated.Experimental investigations were conduct to measure the workability,compressive strength,bending strength,total charge passed and frost resistance of PVA fiber concrete in fresh water and NaCl solution freeze-thaw environment.For frost resistance,the relative dynamic modulus of elasticity and the relative mass change of specimens at each cycle were measured.In addition,the surface deterioration of concrete specimens was also observed.Specimens having different volume content of fiber were tested in order to find the optimization PVA fiber content under freeze-thaw condition.Six series of specimens with PVA fiber volume content of 0%,0.1%,0.25%,0.5%,0.75% and 1.0% were tested.
