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
