Consolidated Construction Consortium Civil Engineer-Highway/Roadway Interview Questions and Answers

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...read more

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...read more

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...read more
