7.4.3. Estimate Binder Content

Try these first

1. 1.

   What is meant by binder content in HPC?

   Hint

   Think of what materials are mixed in.

2. 2.

   Name two types of supplementary cementitious materials.

   Hint

   Consider common additions to concrete for performance.

3. 3.

   What is the typical binder content range for High Performance Concrete?

   • 100-300 kg/m³
   • 200-400 kg/m³
   • 400-600 kg/m³

   Hint

   Consider how HPC deals with extreme conditions.

4. 4.

   Is Silica Fume usually 5-10% of binder content in HPC?

   • True
   • False

   Hint

   Think about how silica fume improves strength.

5. 5.

   You are tasked with designing an HPC mix needing a compressive strength of 90 MPa. What binder content and SCM proportions might you choose for optimal performance? Justify your choices.

   Hint

   Think of common guidelines for compressive strength correlations.

6. 6.

   Analyze how the choice of different SCMs affects the cost and performance of the binder content in an HPC mix aimed at marine environments.

   Hint

   Consider the impacts of various materials on cost and performance metrics.
