Al-Rehmat Glass Quality Assurance Incharge Interview Questions and Answers

Q1. What is contrete?
Ans. 
Concrete is a composite material made from cement, water, aggregates, and additives, used in construction for its strength and durability.
• Concrete is composed of cement, water, sand, and gravel or crushed stone.

• It hardens over time through a chemical process called hydration.

• Common uses include building foundations, roads, bridges, and sidewalks.

• Different types of concrete include reinforced concrete, pre-stressed conc

Q2. What tests are necessary for assessing cement quality?
Ans. 
Assessing cement quality involves various tests to ensure its strength, durability, and suitability for construction.
• Fineness Test: Determines the particle size of cement; finer cement has a higher surface area for hydration.

• Setting Time Test: Measures the time taken for cement to set; initial and final setting times are crucial for workability.

• Compressive Strength Test: Assesses the strength of cement by testing its a...read more

Q3. What is the required mixing time for concrete as specified by the IS code?
Ans. 
IS codes specify a minimum mixing time for concrete to ensure uniformity and strength, typically around 2 to 5 minutes.
• The minimum mixing time for concrete is generally 2 minutes for a concrete mixer.

• For larger batches, the mixing time can extend to 5 minutes to ensure proper consistency.

• Different types of mixers may have varying mixing times; for instance, a pan mixer may require less time than a drum mixer.

Q7. What is the density of concrete?
Ans. 
Concrete density typically ranges from 2,200 to 2,500 kg/m³, depending on the mix and materials used.
• Standard concrete density is about 2,400 kg/m³.

• Lightweight concrete can have a density as low as 1,600 kg/m³.

• High-density concrete can exceed 3,000 kg/m³, often used for radiation shielding.

• The density of concrete affects its strength, durability, and thermal properties.

Q9. Temperature of Curing tank as per is
Ans. 
Curing tanks should maintain specific temperatures for optimal material properties as per industry standards.
• Curing temperature typically ranges from 20°C to 30°C for most concrete applications.

• Higher temperatures can accelerate curing but may lead to cracking if not controlled.

• For certain materials, like epoxy, curing temperatures can be as high as 60°C.

• Monitoring temperature is crucial to ensure proper hydration and
