Q: According to Power's formula the theoretical compressive strength of a sample of concrete with gel space ratio 0.59 is :
  • A. 78.84 MPa
  • B. 49.29 MPa
  • C. 97.24 MPa
  • D. 57.2 MPa
Correct Answer: Option B - Given, Gel space ratio (x) = 0.59 Theoretical compressive strength = 240x³ = 240×(0.59)³ = 49.29 MPa
B. Given, Gel space ratio (x) = 0.59 Theoretical compressive strength = 240x³ = 240×(0.59)³ = 49.29 MPa

Explanations:

Given, Gel space ratio (x) = 0.59 Theoretical compressive strength = 240x³ = 240×(0.59)³ = 49.29 MPa
