4 cards from this section. Quick, good the night before a test.
What is the main goal of the compressive strength test?
Think about the weight concrete structures need to support.
Name one type of bond observed in bond strength testing.
Think about how concrete interacts with steel reinforcement.
What does the compressive strength test measure?
Think about how concrete behaves under pressure.
True or False: The bond strength test evaluates the interactivity between concrete and air.
Focus on where and what materials are being tested.
Given a concrete sample with a cross-sectional area of 2000 mm² that failed at a load of 400 kN during a compressive strength test, determine the compressive strength.
Convert kN to N carefully.
A flexural strength test is conducted on a beam measuring 150 mm x 150 mm x 700 mm, failing at 3000 N. Calculate the flexural strength using third-point loading.
Ensure you know the span and placement of your loads.
