In developing country use of concrete is very high and availability of raw material is comparatively less. Total replacement of concrete is not possible due to no material plays the role of concrete in terms of strength, durability, and workability. To obtain the results, tests are conducted with respect to The Indian Standards for Mix Design IS 10262 (2009) and Scheme of Testing and Inspection - Bureau of Indian Standards to determine the compressive strength of concrete after heating at 200°C temperature for steel fibre Recycled Aggregate Concrete. The natural aggregate is replaced 20% by recycled aggregate and steel fibres are added by volume (0.5%, 1%, and 1.5%). Results of this tests supports the hypothesis that this type of Concrete Mix may be suitable for partial substitution after proper Mix Designing. Aim of this study is to suggest alternate low-cost and environment suitable building materials from industrial wastes in an economic way with good compressive strength than normal concrete. Investigation suggests successful use of steel fibres in concrete for construction activities.
