Abstract :

  Slurry infiltrated fibre reinforced concrete (SIFCON), is fibre reinforced concrete (FRC) in which coarse aggregates are absent. In SIFCON higher percentage of fibres, in the range of 6-20% (by volume fraction) can be used. Cement mortar slurry is infiltrated into a bed of fibres to produce SIFCON. It can be produced using a variety of fibres.
 In this paper effect of temperature on the properties of SIFCON is reported. Fibres used in the experimentation are waste coiled steel fibres obtained from lathe machine shop.  In this study fibres having aspect ratios like 80, 90, 100, 110 and 120 are used.  Different sets of specimens are subjected to temperatures of  200oC for 24 hours. They are tested after cooling at room temperature. The strength characteristics like compressive strength, tensile strength, and flexural strength and impact strength are evaluated.

Key Words: SIFCON, aspect ratio, waste coiled steel fibres, temperature, compressive strength, tensile strength, flexural strength, and impact strength.
