Interview questions for Civil Site Execution Engineer covering topics such as point of contrafrection, soil bearing capacity, types of beams/columns/slabs, PT slab, earthquake zones, parapet height requirements, slum ratio, aggregate quality check, etc.

Point of contrafrection is the point where the bending moment is zero in a beam
Soil bearing capacity is the maximum load that can be applied to the soil without causing failure
Types of beams include simply supported, cantilever, continuous, etc.
Types of columns include rectangular, circular, square, etc.
PT slab is a post-tensioned slab that uses high-strength steel strands to reinforce the concrete
To cast a PT slab, first, the concrete is poured and allowed to partially set. Then, the steel strands are tensioned and anchored to the edges of the slab.
Before plastering, check for any cracks or defects in the wall surface and ensure that it is clean and dry.
Ahmedabad is located in Zone III of the earthquake zone map of India.
The minimum height requirement for parapet walls for B.U permission is typically around 1 meter.
The slum ratio for footing and slab is typically around 1:3:6 (cement:sand:aggregate)
To perform a slum test, a slump cone is filled with concrete and then lifted vertically. The amount of slump (or settling) is measured to determine the workability of the concrete.
The grade of concrete used for column casting depends on the load-bearing capacity required. For example, M20 grade concrete is commonly used for residential buildings.
To check the quality of 20mm and 10mm aggregates, perform tests such as sieve analysis, water absorption test, and crushing value test.
