바닥재용 번드렉스는
slab-on-ground has already been used in advanced countries for large warehouses, factories, superstores, and so forth. By mixing steel fiber with slab-on-ground, improvement can be made for tensile strength, bending strength, resistance to cracking, toughness, shearing strength, resistance to impact and etc.
With reduction of construction cost, it ensures safety and easy constructability. Therefore, a large amount of it is consumed domestically.
번드렉스로 보강된 바닥 슬래브의 특징
  • Superior resistance to cracking due to controlling progress of internal cracking by steel fiber (control of hair crack and drying shrinkage crack)
  • Increased toughness (residual strength) with the rise in steel fiber contents
  • Increased toughness with tensile force transmitted to crack-crossing steel fiber after cracking
  • Increased bending strength
  • Increased ductility (durability) of concrete
  • Ductile fracture behavior
