Nagarjuna Construction Company International Junior Engineer Civil Interview Questions and Answers

Flemish bond brick masonry is considered good due to its strength, durability, and aesthetic appeal.

• Flemish bond brick masonry is known for its strong and durable structure.

• It provides a visually appealing pattern with alternating headers and stretchers in each course.

• The bond helps in distributing the load evenly across the wall.

• Other types like English bond and Stretcher bond are also commonly used in brick masonry.

PCC stands for Plain Cement Concrete.

• PCC is a construction material made by mixing cement, sand, and aggregate with water.

• It is used as a base for flooring, foundations, and other structural elements.

• PCC provides a smooth and level surface for further construction work.

• Example: PCC is commonly used in constructing pathways and driveways.

Workability is the ease with which a material can be worked or shaped.

• Workability is an important factor in construction materials such as concrete and mortar.

• It is affected by factors such as water content, aggregate size and shape, and temperature.

• A material with good workability is easy to mix, place, and finish.

• For example, a concrete mix with high workability can be easily poured into formwork and will flow to fil...read more

Mixing time in concrete is the duration required to achieve a homogeneous mixture of all the ingredients.

• Mixing time depends on the type of mixer used.

• It also depends on the quantity of ingredients and their properties.

• The ideal mixing time is usually specified by the manufacturer or as per the design requirements.

• Over-mixing can lead to a decrease in the strength of concrete.

• Under-mixing can result in the formation of

Dedo is a term used in construction for the leveling of the foundation of a building.

• Dedo is the process of marking the level of the foundation of a building.

• It is done to ensure that the foundation is level and stable.

• It is usually done using a spirit level and a measuring tape.

• Dedo is important for the safety and stability of the building.

• It is also important for the proper alignment of walls and columns.

• For example,...read more

IS code for RCC is IS 456:2000 and for mix design of concrete is IS 10262:2009.

• IS 456:2000 provides guidelines for the design and construction of reinforced concrete structures.

• IS 10262:2009 provides guidelines for the proportioning of concrete mixes based on the desired strength and workability.

• Both codes are important for ensuring the quality and durability of concrete structures.

The spacing of main bar and distribution bar depends on the design and load requirements of the structure.

• The spacing is determined by the structural engineer during the design phase.

• It varies depending on the size and shape of the structure, as well as the load it will bear.

• The spacing should be such that the reinforcement is evenly distributed throughout the structure.

• For example, in a slab, the spacing of main bars ...read more

The minimum diameter of a circular column depends on various factors such as load, height, and material.

• The minimum diameter of a circular column is determined by the maximum load it needs to support.

• The height of the column also influences the minimum diameter as taller columns require larger diameters for stability.

• The material used for construction affects the minimum diameter as different materials have different s...read more

There are several tests conducted on concrete to ensure its quality and strength.

• Some common tests for concrete include compressive strength test, slump test, and water absorption test.

• Compressive strength test measures the maximum load a concrete sample can bear before failure.

• Slump test measures the consistency and workability of fresh concrete.

• Water absorption test determines the amount of water absorbed by concrete...read more
