Abstract

Results of an investigation conducted to study the water permeability of (HySFRC) are presented. Steel fibers of different lengths, i.e., 12.5, 25 and 50 mm having constant diameter of 0.6 mm were systematically combined in different mix proportions to obtain mono, binary and ternary combinations corresponding to 0.5, 1.0 and 1.5% fiber volume fractions. A reference concrete mix containing no fibers was also cast for comparison purpose. A total number of 480 cube specimens of size 100 × 100 × 100 mm were tested for water permeability at 7, 28, 90 and 120 days of curing. Though the compressive strength and split tensile strength tests were also conducted, the results are not reported in this paper. However, the results of compressive strength tests and split tensile tests have been used to arrive at the most appropriate fiber combination. It has, therefore, been observed that a fiber combination of 33% 12.5 mm + 33% 25 mm + 33% 50 mm long fibers can be adjudged as the most appropriate combination to be employed in HySFRC for water permeability, compressive strength and split tensile strength requirements.  Keywords: Compressive strength, fiber reinforced concrete, hybrid steel fiber reinforced concrete, water permeability
