چکیده مقاله:
In this study, an experimental study of new types of polypropylene fibers entitled Barchip (HPP fiber) has been conducted to investigate the usage of this fiber in water tunnel lining. In this study, concrete mixtures with 0.4,0.6 and 0.8 volume percent of HPP fiber and steel fibers were provided. Changes in water absorption, permeability of concrete and chloride penetration depth and abrasion strength were measured relative to the control sample. All tests were undertaken according to ASTM and BS requirements. The results showed that with application of HPP fibers, durability and serviceability of the concrete linings could be remarkably extended.
