This study is performed to evaluate freezing and thawing properties of polypropylene fiber reinforced eco-concrete using soil, natural coarse aggregate, soil compound and polypropylene fiber.The mass loss ratio is decreased with increasing the content of natural coarse aggregate and soil compound, but it is increased with increasing the content of polypropylene fiber.The ultrasonic pulse velocity, dynamic modulus of elasticity and durability factor are increased with increasing the content of natural coarse aggregate and soil compound, but it is decreased with increasing the content of polypropylene fiber.The mass loss ratio, ultrasonic pulse velocity, dynamic modulus of elasticity and durability factor are 1.49~3.32%, 1,870~2,465m/s, 77X10²~225X10² MPa and 84.6~92.8 after freezing and thawing 300 cycles, respectively.These eco-concrete can be used for environment-friendly side walk and farm road.
