Aa Pmc and Engineering Interview Questions and Answers

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 f...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

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.

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 factor...read more

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 cardiovasc...read more

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 ...read more

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 ...read more

The batching time for one lot of RMC varies depending on the size of the batch and the equipment used.

• Batching time can range from a few minutes to an hour or more.

• Factors affecting batching time include batch size, equipment efficiency, and mix design complexity.

• For example, a small batch of RMC may only take a few minutes to batch, while a larger batch with complex mix design could take an hour or more.
