There are different types of cement grades used in construction, each with specific properties and applications.
Ordinary Portland Cement (OPC) is the most commonly used cement grade.
Portland Pozzolana Cement (PPC) contains pozzolanic materials like fly ash, which enhances its strength and durability.
Rapid Hardening Cement (RHC) gains strength quickly and is used in situations where early strength is required.
Low Heat C...
Tests of aggregate in civil engineering are important to ensure quality and durability of roadways.
Aggregate tests include sieve analysis, specific gravity, absorption, and abrasion resistance.
Sieve analysis determines the particle size distribution of the aggregate.
Specific gravity measures the density of the aggregate compared to water.
Absorption measures the amount of water absorbed by the aggregate.
Abrasion resista...
CBR test is a measure of soil strength and bearing capacity.
CBR stands for California Bearing Ratio.
It is a penetration test that measures the strength of soil and its ability to bear loads.
The test involves compacting soil into a mold and measuring the force required to penetrate it with a plunger.
The ratio of the force required to penetrate the soil to the force required to penetrate a standard material is the CBR va...

The Grade of GSB at my previous site was 40 mm.
The Grade of GSB at my previous site was 40 mm.
GSB stands for Granular Sub Base.
The thickness of GSB is usually specified in millimeters.
GSB is a layer of compacted granular material used as a base for asphalt, concrete, or other paving materials.
Tolerances in base and sub-base coarse materials are critical for ensuring proper compaction and stability of the highway.
Tolerances for base coarse typically range from +/- 20mm to +/- 40mm depending on the specified thickness.
Tolerances for sub-base coarse are usually wider, ranging from +/- 50mm to +/- 100mm.
Proper compaction is essential to meet these tolerances and ensure the structural integrity of the highway.

MDD is Maximum Dry Density, FDD is Field Dry Density. MDD is the maximum density achieved by compacting soil in the lab, FDD is the density achieved in the field after compaction.
MDD is determined through laboratory tests using standard compaction methods.
FDD is measured in the field using a nuclear density gauge or sand cone method.
MDD is used to determine the optimum moisture content for compaction.
FDD helps in asses...

I applied via AmbitionBox and was interviewed before Jul 2023. There was 1 interview round.
WMM stands for Wet Mix Macadam, which is a type of road construction method using a mixture of aggregates and water.
WMM is a type of road construction method used for laying base and sub-base layers of roads.
It involves mixing aggregates like stone, sand, and gravel with water to form a strong base.
WMM is often used in highway construction to provide a stable foundation for the road surface.
The mixture is compacted usi...
GSB material name refers to the type of material used in construction and maintenance of highways.
GSB stands for Granular Sub Base
Common materials used for GSB include crushed stone, gravel, and sand

I applied via Referral and was interviewed in Jul 2021. There was 1 interview round.
The quantity of material a roller can compact in one day depends on various factors.
The type and size of the roller will affect its compaction capacity.
The type and condition of the material being compacted will also impact the quantity that can be compacted.
The speed and efficiency of the operator operating the roller can influence the daily compaction quantity.
Environmental factors such as weather conditions and terr...
