Point Load Test Conducted by IIT - Hyd

  • What we propose: The use of STARK STEEL as Reinforcement , by REPLACING the conventional TMT Bars, Steel Fibres, Weld Mesh with our STARK STEEL Rods
  • STARK STEEL can be used as Reinforcement for CONCRETE FLOOR SLABS as per TR 34 4th Edition or IS 456 Standards
  • Tests Conducted: Four slabs each of size 1mtr x 1mtr x 170mm & 1mtr x 1mtr x 150mm were casted. We subject the Concrete Slabs to PUNCHING / POINT LOAD testing method. The tests were conducted at IIT Hyderabad under the supervision of the respected Dr . S. SURIYA PRAKASH, Professor Dept. of Civil Engineering, IIT Hyderabad. The results were;
