Galaxy Corporation Interview Questions and Answers

The minimum thickness of ceiling plastering is 6mm.

• The thickness of ceiling plastering depends on the type of plaster used.

• For cement plaster, the minimum thickness is 6mm.

• For gypsum plaster, the minimum thickness is 9mm.

• The thickness may vary depending on the condition of the ceiling surface.

• It is important to ensure that the plaster is applied evenly and smoothly.

Shuttering quantity can be taken by calculating the surface area of the structure to be casted.

• Calculate the surface area of the structure to be casted

• Determine the thickness of the shuttering material

• Multiply the surface area by the thickness to get the shuttering quantity

• Consider the wastage factor while calculating the quantity

• Example: If the surface area of the structure is 100 sq. m and the thickness of the shuttering material is 0.1 m, then the shuttering quantity requi...read more

Plastering quantities can be calculated by measuring the surface area and thickness of the plaster.

• Measure the length and height of the surface to be plastered

• Calculate the surface area by multiplying the length and height

• Determine the required thickness of the plaster

• Multiply the surface area by the thickness to get the plastering quantity

• Add 10-15% extra for wastage and uneven surfaces

Fine aggregate and coarse aggregate are types of materials used in construction.

• Fine aggregate is a material that is smaller than 4.75mm in size, such as sand.

• Coarse aggregate is a material that is larger than 4.75mm in size, such as gravel or crushed stone.

• Both types of aggregate are commonly used in concrete and other construction applications.

• The ratio of fine to coarse aggregate in concrete mixtures can affect the strength and durability of the final product.

One way slab is a type of reinforced concrete slab that is supported by beams on two opposite sides. Two way slab is supported by beams on all four sides.

• One way slab is designed to carry the load in one direction only

• Two way slab is designed to carry the load in both directions

• One way slab is economical for small spans and light loads

• Two way slab is suitable for larger spans and heavy loads

• Examples of one way slab include balcony slabs, roof slabs, and floor slabs

• Examples of...read more

Development length is the length of reinforcement required to transfer the stress from steel to concrete.

• It is the minimum length of reinforcement bar required beyond the point of maximum stress.

• It ensures that the steel reinforcement bars do not slip from their position.

• It depends on the diameter of the reinforcement bar, the grade of concrete, and the bond strength between steel and concrete.

• For example, the development length of a 20mm diameter bar in M25 grade concrete is...read more
