BEHAVIOUR OF STRUCTURAL ELEMENTS CONTAINING GOLD MINE TAILINGS AS PARTIAL SUBSTITUTE FOR NATURAL SAND

Natural sand is becoming a scares material and the current research on building materials mainly focus on finding an alternative material for natural sand. In this investigation, an attempt is made to use gold mine tailings as a partial substitute for natural sand. Concrete of grade M25 is obtained as per IS 10262 natural fine aggregates are replaced with 10%, 20% and 30% gold mine tailings. Structural elements such as beams, slabs and columns are casted with the resulting fine aggregates. The behaviour of beams and slabs under flexu axial compression is studied. of resulting sand reduces. The ultimate loads in case of beams, slabs and columns are slightly higher than the control elements for 10% replacement. For 20% and 30% replacements, the ultimate loads a are also studied. Results show that gold mine tailings have the potential of being used as a partial substitute material for natural sand
