3.3. Causes

Try these first

1. 1.

   What is segregation in concrete?

   Hint

   Think about how the different sizes of aggregates might not stay mixed together.

2. 2.

   Define bleeding in concrete.

   Hint

   Consider what happens when solids settle in a liquid.

3. 3.

   What is segregation in concrete?

   • Uniform distribution of aggregates
   • Separation of concrete components
   • Increased workability

   Hint

   Consider how different densities can lead to separation.

4. 4.

   True or False: Bleeding is beneficial to concrete.

   • True
   • False

   Hint

   Think about how excess water affects material strength.

5. 5.

   Design a mix with a balanced water-cement ratio to mitigate segregation, considering types of aggregates.

   Hint

   Research optimal ranges for your specific project conditions.

6. 6.

   Evaluate a concrete sample showing signs of bleeding. What steps would you take to remedy the situation before pouring?

   Hint

   Consider the properties of the materials involved.
