Admixtures are used to modify the properties of concrete, such as setting time, workability, and strength.
To improve workability of concrete
To reduce water content in concrete
To accelerate or retard setting time of concrete
To improve strength and durability of concrete
To reduce corrosion of reinforcement in concrete
Examples: water reducers, air-entraining agents, accelerators, retarders, superplasticizers
We use Portland Pozzolana Cement (PPC) in PQC.
PPC is a type of cement that is commonly used in PQC.
It is a blend of Portland cement and pozzolanic materials like fly ash, volcanic ash, etc.
PPC is preferred over Ordinary Portland Cement (OPC) due to its higher durability, strength, and resistance to chemical attacks.
It also has a lower heat of hydration, which reduces the risk of thermal cracking.
Examples of PQC project...

I applied via Walk-in and was interviewed in Jan 2024. There were 2 interview rounds.
A cross section of a road is a vertical slice through the road showing the various layers and components.
A cross section typically includes the road surface, base course, subbase, and natural subgrade.
It helps engineers understand the composition of the road and plan for construction or maintenance.
Cross sections are used to determine the appropriate materials and thickness for each layer of the road.
Examples of cross ...

There are two main types of pavement: flexible pavement and rigid pavement.
Flexible pavement is made up of multiple layers of materials like asphalt and is designed to be flexible to distribute loads over a wider area. Example: asphalt concrete pavement.
Rigid pavement is made up of a single layer of concrete and is designed to be stiff and strong. Example: jointed plain concrete pavement.
Core cutting is a process of extracting cylindrical samples from a structure or material for testing purposes.
Core cutting is commonly used in construction and civil engineering to assess the quality of materials used in structures.
The extracted core samples are typically analyzed for strength, density, composition, and other properties.
Examples of core cutting applications include testing concrete strength in building...
Dense Bituminous Macadam is a type of road construction material made up of well-graded aggregates and bitumen binder.
Consists of well-graded aggregates like crushed stone, gravel, or sand
Bound together by bitumen binder
Provides a strong and durable road surface
Used in highways, airport runways, and heavy traffic areas
I applied via Approached by Company and was interviewed before Oct 2022. There were 3 interview rounds.
I applied via Referral and was interviewed in May 2021. There was 1 interview round.
OpenRoads is a civil engineering software used for designing and analyzing transportation infrastructure.
OpenRoads allows for 3D modeling of roads, bridges, and highways.
It includes tools for surveying, terrain modeling, and drainage design.
The software also has features for analyzing traffic flow and safety.
OpenRoads can integrate with other civil engineering software such as MicroStation and InRoads.
The working proce...
