Quicksand is a-
Detailed Solution for APSC AE CE Paper 1 Mock Test - 6 - Question 6
Quick Sand condition If the seepage pressure becomes equal to the pressure due to the submerged weight of the soil, then evidently, the effective pressure is reduced to zero. In such a limiting case, the Cohesionless soil loses all its shear strength, and the soil particles will tend to move up in the direction of flow. This phenomenon of the lifting of soil particles is called the quick condition or boiling condition, or quick sand. The hydraulic gradient corresponding to this situation (Just starting) is called critical hydraulic gradient ((ic)) Where,

A doubly reinforced beam is considered less economical than a singly reinforced beam because
Detailed Solution for APSC AE CE Paper 1 Mock Test - 6 - Question 11

For doubly reinforced section, tension reinforcement is designed for stress of 0.87fy but for compression reinforcement a lower stress must be used. The reason being that steel may buckle between shear stirrups under compressive stresses. And hence doubly reinforced beam is considered less economical because compressive steel is under stressed.

The main objective of compaction of concrete is:
Detailed Solution for APSC AE CE Paper 1 Mock Test - 6 - Question 29
Compaction of concrete is the process adopted for expelling the entrapped air as far as possible from the concrete to achieve the highest possible density of the compacted mass.

  • Compaction improves the fluidity of concrete and with the reduction of internal friction, packing of coarse aggregates take place

  • A well-compacted concrete is free of the loose pockets and air bubbles of entrapped air

  • The main purpose of compaction of concrete is to get a dense mass without voids, to get the concrete to surround all reinforcement, and to fill all corners i.e. to provide intimate contact between the concrete and embedded materials
