SOLUTIONS

S1. Ans.(b)
Sol. Tricalcium aluminate is responsible for flash setting of cement.

S2. Ans.(b)
Sol. According to IS 10500:2012, the acceptable limit of total dissolved solids in drinking water is 500 mg/l and cause for rejection is 2000 mg/l.

S3. Ans.(a)
Sol. Hydrodynamic pressure due to earthquake is Fe= 0.555k_h γ_wH² and it is acts at a height of 4H/3π above the base of dam. Where H=seepage head, γ_w=unit weight of water, k_h=seismic coefficient.

S4. Ans.(b)
Sol. fly levelling is used for reconnaissance of the area. Purpose of this levelling for determination of approximate elevation of points.

S5. Ans.(b)
Sol. There are Infinite planes passes through a single point. Out of these infinite planes three planes are mutually perpendicular to each other and having zero shear stress, these planes are called principal plane.

S6. Ans.(d)
Sol. The unit of measurement for mass concrete is cubic meter.

S7. Ans.(b)
Sol. desire lines is used in Origin and destination studies.

S8. Ans.(c)
Sol. Pycnometer is used for determination of specific gravity.

S9. Ans.(a)
Sol. Reynold’s No. (Inertial force)/(Viscous force)
S10. Ans.(a)
Sol.
