Concrete is a mixture of cement, water, aggregates, and sometimes additives, used in construction for its strength and durability.
Concrete is made up of cement, water, and aggregates (such as sand and gravel)
It is a versatile material used in construction for buildings, roads, bridges, and more
Additives can be included in concrete mixtures to enhance specific properties, such as strength or workability
Concrete hardens ...
Structure in civil engineering refers to the arrangement and organization of elements in a building or infrastructure to support loads and resist forces.
Structure is the framework or skeleton of a building or infrastructure that supports the weight of the building and its occupants.
It includes elements such as beams, columns, walls, and foundations that work together to provide stability and strength.
Structural design ...
I applied via Naukri.com and was interviewed in Jul 2024. There were 3 interview rounds.
Rolling margin in steel consumption refers to the percentage of excess steel ordered to account for potential wastage during the manufacturing process.
Rolling margin is typically around 5-10% of the total steel consumption.
It helps to ensure that there is enough steel available to complete a project without running out.
Factors such as the complexity of the project and the experience of the manufacturer can influence th...
I applied via Walk-in and was interviewed before Nov 2023. There was 1 interview round.
Different grades of concrete are used for different structures based on their strength requirements.
Different grades of concrete like M5, M10, M15, M20, M25, etc. are used for different structures.
For example, M5 grade concrete is used for PCC (Plain Cement Concrete) work, while M20 grade concrete is used for RCC (Reinforced Cement Concrete) work.
Higher grades like M30, M35, M40, etc. are used for structures requiring
D-wall stands for Diaphragm wall, a reinforced concrete wall constructed in the ground to support excavation and prevent water ingress.
D-wall is commonly used in deep excavation projects to provide lateral support and prevent soil movement.
It is constructed by excavating a trench, installing reinforcement bars, and pouring concrete into the trench.
D-walls are often used in construction of underground structures like ba...
In high water level areas, foundation work involves dewatering techniques to lower the water table and ensure stability.
Dewatering techniques such as wellpoint systems, deep wells, sumps, and pumping are used to lower the water table.
Waterproofing measures like using impermeable membranes or grouting can be applied to prevent water infiltration.
Proper drainage systems are installed to divert water away from the foundat...

Grade of concrete refers to the strength of the concrete mix measured in terms of compressive strength.
Grade of concrete is denoted by the ratio of cement to sand to aggregate in the mix.
Common grades of concrete include M20, M25, and M30, where 'M' stands for mix and the number denotes the strength in MPa.
Higher grade concrete mixes have higher compressive strength and are used for structural purposes.
The grade of con...
Concrete testing involves various methods to ensure quality and durability.
Testing for compressive strength using a concrete cube or cylinder
Checking for workability through slump test or flow table test
Measuring air content to ensure proper freeze-thaw resistance
Evaluating setting time with penetration resistance test or Vicat test
Assessing durability with water absorption test or chloride ion penetration test
Precautions for safety in civil engineering include proper training, use of personal protective equipment, regular inspections, and following safety protocols.
Provide proper training to all workers on safety procedures and protocols
Ensure all workers use appropriate personal protective equipment (PPE) such as hard hats, gloves, and safety glasses
Conduct regular inspections of equipment and work sites to identify and ad...
