in environment and economy development. Key words: roadbed filling; unconfined compression strength; shear strength; cement and fiber reinforcement; heavy metal contaminated soil Cite this article... and decrease the stiffness of soil. More importantly, as compared to soil alone or cement stabilized soil, the soil with fiber reinforcement exhibits higher ductility and less loss of post-peak residual......
fiber give birth to bridge function and reinforcement, and forms a three-dimensional network in asphalt. This three dimensional structure of fibers can assist in the formation of a thicker structure... and reinforcement. The reinforcement of polyester fiber is more obvious, but the stability of cellulose fiber remains prominence. 4) On the basis of viscoelastic properties, the criteria used to select......
, and found that 30% fly ash and 1% fiber provides the optimum content, and the inclusion of fiber reinforcement has positive benefits on the mechanical properties of the reinforced soil. The above... in this test, and the loading rate was kept at 2.4 mm/min. Scanning electron microscopy (SEM) was used to record the internal microstructure and fiber reinforcement surface of the PUR and PF-reinforced......

With the example of a certain tunnel......
analyzed by Weibull model. In addition, the tensile strength of composites was investigated as well. 2 Experimental 2.1 Materials Bamboo fiber(BF) as reinforcement in composites was produced...J. Cent. South Univ. Technol. (2008) 15(s1): 564-567 DOI: 10.1007/s11771-008-422-z Evaluation of statistical strength of bamboo fiber and mechanical properties of fiber reinforced green......
without the special confining reinforcement. In particular, composite with higher volume steel fiber increases the flexural strength than the lesser volume composite but affects the ductility. The use... composite prepared with twisted steel fiber and PE fiber shows better shear resistance without closely spaced transverse steel reinforcement and also shows slower rate stiffness degradation [22......
less influence on the load-carrying capacity. Key words: beam; fiber reinforced polymer (FRP); stainless steel; prestress; deformability; reinforcement ... fiber reinforced polymer (FRP) tendons and stainless steel reinforcing bars was simulated using a simplified theoretical model. The model assumes that a section in the beam has a trilinear moment......
