An Experimental Study on the Effect if Fiber Reinforced on CFRD Face Slab Concrere

CFRD (Concrete Faced Rockfill Dam) face slab concrete has a much capability to occur crack due to drying shrinkage, hydration heat and bas compaction etc. Because of crack of concrete induce structural problem and decrease durability of concrete, it is need to reduce crack of concrete. This is an experimental study to analyze the effect of fiber reinforced on CFRD face slab concrete. for this purpose, it was investigated and analyzed the engineering properties of plain concrete and polypropylene fiber reinforced concrete (PFRC) according to test result ; the test include slump, air content, compressive strength, tensile strength, drying shrinkage and permeability etc. As the results, it was found permeability and drying shrinkage of PFRC less than that of plain concrete.
