The Effect of Organic Fibers on Crack Resistance of Concrete and Applicable for Secondary Lining
In this paper, concrete incorporated organic fibers, i.e., polyvinyl alcohol fiber (PVA fiber), polypropylene fiber (PP fiber), cellulose fiber (UF fiber), polyethylene fiber (PETF) was produced. The properties measured included strength and crack resistance performance of the concrete. The effect of organic fibers on the crack resistance properties was investigated. Test results indicated that the organic fibers of different types could reduce the size and amount of crack source; organic fibers provided better enhancement for shrinkage resistance of concrete; Cellulose fiber concrete applied for secondary lining under the Ⅲ wall rock, both work performance and strength index satisfy the design demand, and concrete surface cannot detect crack after 280 days.
