2. Mixing of Concrete

Try these first

1. 1.

   What is hand mixing of concrete?

   Hint

   Think about how concrete might be mixed for a backyard path.

2. 2.

   What is the benefit of machine mixing?

   Hint

   Consider how difficult consistency can be in manual processes.

3. 3.

   What is the primary purpose of mixing concrete?

   • To ensure uniformity
   • To increase strength
   • To reduce labor

   Hint

   Think about what uniformity means for the strength of the concrete.

4. 4.

   True or False: Ready Mix Concrete is mixed on-site.

   • True
   • False

   Hint

   Recall where the mixing of RMC actually takes place.

5. 5.

   Design a concrete mix for a small terrace. Considering the project will use hand mixing, what proportions would you suggest to achieve sufficient strength?

   Hint

   Think about what strength and durability are needed for a small structure.

6. 6.

   In a high-rise construction project, why would a civil engineer prefer using RMC over traditional mixing methods?

   Hint

   Consider the benefits of consistency and time management with RMC.
