Concrete Testing – FAQ & MCQ

FAQs (5–7)

1. What is concrete testing?
   Testing concrete evaluates its strength, durability, and quality to ensure it meets construction standards.
2. Why is concrete testing important?
   To ensure safety, structural integrity, and compliance with engineering specifications.
3. What are common types of concrete tests?
4. • Compressive strength test
   • Slump test
   • Flexural strength test
   • Air content test
5. What is a slump test?
   A measure of concrete’s workability and consistency before it sets.
6. How is compressive strength measured?
   Using a compression testing machine on concrete cubes or cylinders after curing.
7. What factors affect concrete strength?
   Water-cement ratio, curing time, material quality, and mix proportion.
8. When should concrete be tested?
   At fresh state (workability) and after curing (strength), typically 7, 14, and 28 days.
