SOLUTION

S1. Ans.(c)
Sol. Air permeability test of cement is conducted to find the fineness of cement. It measures surface area.

S2. Ans.(b)
Sol. Slump mould is in the shape of conical frustum.

S3. Ans.(a)
Sol. Most of the light weight aggregates are obtained from volcanic source.
Ex. Basalt, blast furnace slag, natural pumice etc.

S4. Ans.(c)
Sol. Disintegration of bricks is due to the presence of impurities such as stone, kankar nodules and efflorescence which may be due to presence of magnesium sulphate in the bricks.

S5. Ans.(a)
Sol. Modular bricks are the proper bricks for high class brick masonry.

S6. Ans.(a)
Sol. The correct sequence of three stages in sludge digestion process:
(i) Acid regression
(ii) Acid fermentation
(iii) Alkaline fermentation
