4 cards from this section. Quick, good the night before a test.
What does compressive strength indicate about hardened concrete?
Think about what it means for a material under pressure.
What is the purpose of the Rapid Chloride Penetration Test?
Consider why preventing chloride ingress is important.
What does the modulus of elasticity represent in concrete testing?
Think about the behavior of a spring under weight.
True or False: The Rapid Chloride Penetration Test measures concrete's axial strength.
Focus on what the test specifically measures.
A concrete sample exhibits a compressive strength of 70 MPa at 28 days. Discuss how this might influence the design and safety of a structural element in a seismic zone.
Consider how stress and forces interact during an earthquake.
You have a concrete mix that passes RCPT with low permeability results. How would you argue this mix is suitable for a marine application?
Think about the impact of saltwater on concrete.
