| Abstract: | In this paper, the mechanical properties and durability of cement matrix material with low content of PA6 fiber were investigated. The results showed that when 0.05% -0.15% fiber volume fraction of PA6 fiber was added into cement concrete, the compressive strength,the flexural strength and the splitting tensile strength of the fiber concrete were not affected harmfully, the impacting strength of the fiber paste could increase greatly and the anti-frost property of the fiber concrete could be improved. From the result of the aging test,it could be found that the property of the PA6 fiber in cement matrix was not affected by the aging environment. |
