Studies on Evaluation of Durability of Pre-cracked RCC Members Using Fly Ash Concrete

CPWD, New Delhi

  • Types of cement – OPC, PPC
  •  Fly ash Content – 18, 25, 35%
  •  Grades of concrete- M25 & M35
  •  Crack width – 0,0.1,0.2 mm
  •  Accelerated exposures (CO2, Sulphates, Chloride)

Outcome

  • Data base for sulphate resistance and corrosion resistance of cracked steel reinforced PPCC & FACC members to  in carbon  dioxide & chloride environs
  • Durability of fly ash based concretes and PPCCs> OPCCs
  • GO by CPWD on use of PPC & fly ash in concretes
