The Travelmart Interview Questions and Answers

Anti corrosive treatment on reinforcement is a process to protect steel reinforcement from corrosion in concrete structures.

• Anti corrosive coatings are applied on the surface of reinforcement bars to prevent corrosion.

• Common methods include epoxy coatings, galvanization, and corrosion inhibitors.

• These treatments help extend the lifespan of concrete structures and prevent structural damage.

• Proper surface preparation is essential before applying anti corrosive treatments.

• Regula...read more

Environmental exposure conditions refer to the various factors in the environment that can impact an individual's health and well-being.

• Includes factors such as air quality, water quality, noise levels, and presence of hazardous substances

• Can also include factors like temperature, humidity, and access to green spaces

• Examples: exposure to air pollution from traffic, living near a landfill site, working in a noisy factory

Cover in RCC refers to the thickness of concrete between the outer surface of the reinforcement and the outer surface of the concrete.

• Cover protects the reinforcement from corrosion, fire, and other environmental factors.

• It helps in preventing the steel bars from coming in contact with moisture and chemicals present in the environment.

• Proper cover ensures the durability and strength of the structure.

• The required cover thickness varies depending on the type of structure and en...read more

Admixture dosage in concrete is typically between 0.1% to 5% of the total weight of cement used.

• Admixture dosage in concrete is usually between 0.1% to 5% of the total weight of cement.

• Admixtures are added to concrete to improve its workability, durability, and strength.

• Examples of admixtures include water reducers, accelerators, retarders, and air-entraining agents.

The finesse modulus is a measure of the ability of a material to resist deformation under load.

• The finesse modulus is calculated by dividing the stress required to produce a given strain by the strain itself.

• It is commonly used in materials science and engineering to evaluate the stiffness and strength of materials.

• Higher finesse modulus values indicate greater resistance to deformation.

• For example, a material with a finesse modulus of 100 MPa would require 100 MPa of stress ...read more

The quantity of cement required in M25 concrete mix depends on the ratio of cement to other materials.

• The ratio of cement to aggregate to sand in M25 concrete mix is usually 1:1:2

• For 1 cubic meter of M25 concrete mix, the quantity of cement required is approximately 350 kg

• The quantity of cement can vary based on the specific requirements of the project

Delhi's environment exposure condition is characterized by high levels of air pollution, particularly during winter months.

• Delhi experiences severe air pollution due to factors such as vehicular emissions, industrial activities, construction dust, and crop burning in neighboring states.

• The city often faces smog and poor air quality levels, leading to health issues such as respiratory problems, allergies, and cardiovascular diseases.

• Efforts have been made to address the issue,...read more
