This study will not only prove experimental dynamic properties which are classified to slump, compressed strength, bending strength and toughness index blast-furnace cement concrete with polypropylene (PP) fiber that refer properties and volume of it, but also establish a basic data in order to use PP fiber reinforced blast-furnace cement concrete. The slump didn't changed by PP fiber volume 5 kgf/m³ because of flexibility of fiber in despite of loose mixing. The reason why the slump decreased steadily by PP fiber volume 3 kgf/m³ was rising contact surface of water. The compressed strength indicated a range of 19.49∼26.32 MPa. The tensile strength indicated a range of 2.10∼2.44 MPa. The bending strength was stronger about 3∼16 % in case of mixing with PP fiber volume than normal concrete. The flexure strength indicated a range of 4.30∼4.83 MPa. The toughness indicated a range of 0 ∼19.88 N · mm and was stronger about 6.7 times in case of PP fiber volume 9 kg/m³ than PP fiber volume 1 kg/m³. The pavement with PP fiber volume over such a fixed quantity in the roads of a respectable amount load can have a effect to prevent not only resistance against clack but also rip off failures.
