Effects of Fiber Content and Water Ratio on the Strength of Fiber Reinforced Mortar
Abstract:
The compressive and flexural strength of ordinary mortar and fiber reinforced mortar with five different pp fiber content were tested in this paper. The results show that the compressive strength reduced gradually with PP fiber increasing, and the flexural strength increased when the fiber volume fraction is no more than 0.12%. The higher water ratio can weaken the cohesiveness of the fiber and cement material, and the influence of polypropylene fiber on the flexural strength of mortar decreased after soaking. The major strength damage in the process of curing is caused in the early age and appropriate amount of fiber is beneficial to reduce strength damage.
