3 cards from this section. Quick, good the night before a test.
What is the primary equipment used in the compressive strength test?
It's the machine that applies load to the concrete.
What type of test is a pull-out test?
This test evaluates the bond between concrete and steel.
What is the purpose of a compression testing machine in concrete testing?
Think about what strength test uses compression.
True or False: The flexural strength test measures how well concrete holds up under tension.
Consider what forces are at play in bending.
A constructor wants to assess the compressive strength of a concrete cylinder. If the maximum load recorded is 200 kN and the diameter of the specimen is 150 mm, calculate the compressive strength. Provide your work.
Remember to calculate the cross-sectional area using the diameter.
During a flexural test, a beam fails under a load of 45 kN. The beam had a width of 200 mm and a depth of 300 mm with a span of 1200 mm in third-point loading configuration. Calculate the flexural strength.
Use the formula for flexural strength and adjust for the loading configuration.
