Calculate the gel space ratio and therotical
Strength of sample of concrete made with
of cement
rato, on full
hydration and at
60% hydration
500 gen
paste 0.5 WIC​

Answer 1

Answer:

Example: Calculate the gel/space ratio and the theoretical strength of a sample of concrete made with 500 gm. of cement with 0.5 water/cement ratio, on full hydration and at 60 per cent hydration. ∴ Theoretical strength of concrete = 240 x (0.8)3 = 123 MPa Gel/space ratio for 60 percent hydration
