ONE LINER MCQs 

  BUILDING MATERIALS

1. The extent and propagation of cracks in concrete can be controlled by incorporating fibers in the concrete.

2. Light weight concrete is used for non loading bearing and partition walls.

3. Light weight aggregate is produced by sintering fly ash. 

4. Shortcrete is a mortar or very fine concrete deposited by jetting it with high velocity onto the prepared surface.

5. Water reducing agent - Lignosulphonate

6. Vee bee consistometer<slump test< compaction factor test for low to high workability .

7. Splitting tensile strength test of concrete is given by 2P/πDL.

8. Cubical aggregate give max. strength to the aggregate.

9. Grading of aggregate in a concrete mix is necessary to achieve reduction in voids. 

10. Ultrasonic pulse velocity test is a non destructive test.
