State whether the following is true or false.
Cement testing measures the cement rather than the concrete.

  • A.False
  • B.True only at large scales
  • C.False only at small scales
  • D.True

Answer: D

Every variable except the cement is fixed by the standard so that results are comparable between samples and laboratories. Predicting the concrete requires a trial mix using the actual materials. Only the real aggregates and water can answer that question.
