(a) Linen tape
(b) Metallic tape
(c) Steel tape
(d) Invar tape

(a) 72 cum
(b) 2.4 sqm
(c) 24 sqm
(d) 36 cum

Q4. Quick set cement is obtained by:
(a) Reducing C_3 S content
(b) Reducing C_2 S content
(c) Reducing gypsum content
(d) Increasing C_2 S content

Q5. Find the tensile stress of a mild steel rod of 18mm diameter. Given: ultimate load = 9.0 ton.
(a) 0.03 Ton/sq.mm
(b) 0.02 Ton/sq.mm
(c) 0.05 Ton/sq.mm
(d) 0.06 Ton/sq.mm

Q6. The force of attraction between the individual particles bound together is known as
(a) Dilatancy
(b) Adhesive
(c) Cohesion
(d) Internal friction

Solutions

S1. Ans.(b)
Sol. W.C.B = 137°30’
Q.B = ?

Q.B = 180° – 137° 30’
= S 42°30’ E

S2. Ans.(d)
Sol. Invar tape → It is made up an alloy of steel (64%) and nickel (36%). It has very low coefficient of thermal expansion (0.122 × 10^(-6)/°C). It is used for linear measurement of a very high degree of precision. It is least affected by temperature changes.

S3. Ans.(c)
Sol. Given, Length of wall (L) = 4m.
Height of wall (H) = 3 m.
Area of wall = L × H
= 4 × 3 = 12 m²
Quantity of plaster (two faces) = 2 × 12
= 24 m²

S4. Ans.(c)
Sol. Quick set cement is obtained by Reducing gypsum content. It is used for under water construction. It is gypsum free cement. The initial setting time and final setting time for quick cement is 5 min and 30 min. respectively.

S5. Ans.(a)
Sol. Diameter = 18 mm
Ultimate load = 9.0 ton
Tensile stress = (9.0 ton)/(π/4×18²)
= 0.035 ton/mm²

S6. Ans.(b)
Sol. Adhesion → It is an attractive force between different kind of fluid molecules.
Cohesion → It is an attractive force between same kind of fluid molecules.
