Comparative study on influence of different fibers to performance of abrasion resistant concrete

We conducted experimental study on mechanical,deformation and durability performance of abrasion resistant concretes mixed with basalt fiber,polyacrylonitrile fiber and HPP fiber respectively.The results show that the mixed water volume of HPP concrete is 8 kg/m3 more than that in normal concrete;the mechanical and abrasion resistant performance of abrasion resistant concretes is increased by HPP at the largest extent;the shrinkage rate and ultimate tensile elongation of abrasion resistant concrete have relative higher values;the mix of the 3 fibers obviously inhibit self-generating volume change of abrasion resistant concrete;the frost resistant grade and impermeability resistant grade of 3 fiber-mixed concretes and normal concrete all reach W8 and F100.
