Interview Questions and Answers

Plasticizer and superplasticizer are both additives used in construction, but they have different properties and applications.

• Plasticizer is used to improve the workability and flow of concrete by reducing water content.

• Superplasticizer is a more powerful version of plasticizer, capable of significantly increasing the workability of concrete without increasing water content.

• Plasticizer is typically used in applications where a moderate increase in workability is desired, such...read more

The foundation is the lowest part of a building, typically below ground level, that supports and anchors the structure.

• The foundation distributes the weight of the building and prevents settling or movement.

• There are different types of foundations, such as shallow foundations (e.g. strip, raft) and deep foundations (e.g. piles, caissons).

• The type of foundation used depends on factors like soil conditions, building size, and load-bearing requirements.

Concrete is a composite material made of cement, water, aggregates, and sometimes additives, used in construction for its strength and durability.

• Concrete is made by mixing cement, water, and aggregates like sand and gravel.

• It hardens over time through a chemical process called hydration.

• Concrete is used in construction for building foundations, roads, bridges, and more.

• There are different types of concrete, such as ready-mix concrete and precast concrete.

A column is a vertical structural element that supports the weight of the structure above it.

• Columns are typically made of concrete, steel, or wood.

• They are used to transfer loads from the structure above to the foundation below.

• Columns come in various shapes and sizes, such as square, rectangular, or circular.

• Columns can be found in buildings, bridges, and other structures.

• Columns are essential for providing stability and strength to a structure.

The floor is the bottom surface of a room or building on which people walk.

• The floor provides a stable surface for walking, sitting, and placing furniture.

• Different materials can be used for flooring such as wood, tile, carpet, or concrete.

• Flooring can be designed for specific purposes like durability in high-traffic areas or aesthetics in living spaces.
