| Abstract: | Through incorporating different percentage of polypropylence fiber in a lightweight aggregate concrete,the compressive strength,axial compressive strength,modulus of elasticity,flexural strength and bending toughness of the concrete are resereched.At the same time,the releationship between mechanical properties and intensity scale is also compared.Results showed that polypropylence fiber can improve the flexural strength and bending toughness,but the compressive strength is related with the intendity scale. |
