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.
Abstract
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.
