- Abstract
Based on the fiber dispersion and concrete compressive strength tests, the effects of mixing method, mixing time and fiber content on the dispersion performance of ternary copolymer fibers in concrete were studied. The experimental results show that a modified dry mixing method benefits the dispersion of the fibers in concrete and obtains a desirable mechanical performance as compared with wet mixing and ordinary dry mixing methods. With an increase in mixing time, the fiber dispersion coefficient and the compressive strength of concrete increased at initial stage and then decreased. In addition, the fiber dispersion coefficient and the compressive strength of concrete decreased with the increase of fiber content. Taking both the strength properties of the concrete and economic factors into consideration, the modified dry mixing method was considered the most desirable mixing method, with an optimum mixing time of 6 minutes and an ideal fiber content of 0.14%.
