Show hintHide hint
Think about how hard the surface feels.
Question 2.
What does abrasion resistance measure?
Show hintHide hint
Consider wear from traffic on the surface.
3Question 3.
What is the main purpose of measuring surface hardness?
- To determine compressive strength

Show hintHide hint
Consider the effects of too much water.
Question 5.
A manufacturer has a choice between a high and low water-cement ratio for their concrete flooring. Explain the trade-offs between each option and the implications for surface hardness.
Show hintHide hint
Consider the direct effects of water content on concrete strength.
Question 6.
