Question

Group I gives a list of test methods and test apparatus for evaluating some of the properties of Ordinary Portland Cement (OPC) and concrete Group II gives the list of these properties.

Group I

P. Le Chatelier test

Q. Vee – Bee test

R. Blaine air permeability test

S. The Vicat apparatus

Group-II

1. Soundness of OPC

2. Consistency and setting time of OPC

3. Consistency or workability of concrete

4. Fineness of OPC

The correct match of the items in Group I with items in Group II is
1. P-1, Q-3, R-4, S-2
2. P-2, Q-3, R-1, S-4
3. P-4, Q-2, R-4, S-1
4. P-1, Q-4, R-2, S-3

Answer 1

Correct Answer - Option 1 : P-1, Q-3, R-4, S-2

1) Le chatelier Test: This test is used to measure the soundness of OPC due to lime. Lime & Magnesia are two primary compounds responsible for soundness of cement.

2) Vee Bee Test: It is one of the methods of measuring the workability of concrete.

3) Blaine Air Permeability: It is used to measure fineness of cement.

4) The Vicat Apparatus: It is used to measure setting time and consistency of concrete.
