Q: The condition not applicable to water cement ratio law is ................
  • A. Internal moisture conditions on hydration continue till complete strength is gained
  • B. Concrete specimens may be tested at any temperature
  • C. Concrete specimens are needed to be of same age
  • D. Concrete specimens are need to be of same size
Correct Answer: Option B - Water Cement ratio – The strength of concrete depends on water cement ratio but not depend on cement content. Water Cement ratio law condition – (i) Internal moisture condition on hydration continues till complete strength is gained. (ii) Concrete specimen are needed to be of same age. (iii) Concrete specimen test at 27⁰C temperature. (iv) Concrete specimens are needed to be of same size
B. Water Cement ratio – The strength of concrete depends on water cement ratio but not depend on cement content.
