10.2. Hardened Concrete Tests

Try these first

1. 1.

   What does the Compressive Strength Test measure?

   Hint

   Think about what happens when concrete is loaded.

2. 2.

   Why is tensile strength important?

   Hint

   Remember that concrete is strong in compression but weak in tension.

3. 3.

   What is the primary purpose of the Compressive Strength Test?

   • To measure tensile strength
   • To evaluate load-bearing capacity
   • To assess viscosity

   Hint

   Consider what happens when weight is applied to concrete.

4. 4.

   True or False: The Split Tensile Strength Test measures a concrete sample's resistance to compression.

   • True
   • False

   Hint

   What types of stresses are concrete most susceptible to?

5. 5.

   Design a testing regime for a new type of concrete intended for a coastal project. Include the tests you would employ to assess both strength and durability.

   Hint

   Consider environmental factors that might affect the concrete.

6. 6.

   Explain how you would analyze the results from the Flexural Strength Test and what implications these results might have on the final concrete mix design.

   Hint

   Look at balancing strength and cost in your analysis.
