| Abstract: | Steel fibers?polypropylene fibers and hybrid fibers including above two kinds of fibers are used to been reinforcement in lightweight cementitious matrix in this paper.The properties of compressive strength,elastic modulus,axial compressive strength and flexural strength are investigated systematically.The results indicate the factors like types of fiber,volume fraction of fibers and fiber hybrid proportion have effect on mechanical performance of lightweight concrete.When volume fractions of steel fiber and polypropylene fiber are respectively 1.0% and 0.6kg/m3,the mechanical properties of fiber reinforced lightweight aggregate concrete is achieved optimization. |
| Keywords: | lightweight concrete steel fiber polypropylene fiber hybrid fiber mechanical properties |
