Abstract

The paper presents results of an investigation conducted to study the compressive strength and water permeability of hybrid steel fiber reinforced concrete (HySFRC). 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. Mixes with no fibers were also cast for comparison purpose. Three fiber volume fractions, i.e., 0.5, 1.0 and 1.5% were used in the investigation. A total number of 132 cube specimens of size 100 × 100 × 100 mm were tested for compressive strength and water permeability. It has 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 compressive strength and water permeability requirements.
