  • A. P-4, Q-2, R-3, S-1
  • B. P-1, Q-4, R-2, S-1
  • C. P-3, Q-4, R-2, S-1
  • D. P-2, Q-4, R-1, S-3
Correct Answer: Option D - Soundness test–It is essential that the cement concrete does not undergo large change in volume after setting. This is ensured by limiting the quantities of free lime and magnesia which slake slowly causing change in volume of cement. Soundness of cement may be tested by– • Le-Chatelier Method • Auto Clave Method Fineness–The degree of fineness of cement is the measure of mean size of the grains in it. There are three methods for testing fineness– • Air permeability method - Nurse and Blains • Sieve method • Wagner turbidimeter method. Setting time–The setting time of cement are find by Vicat apparatus. Tensile strength–The tensile strength may be determined by briquette test method or by split tensile strength test.
