2 cards from this section. Quick, good the night before a test.
What is the definition of creep in concrete?
Think about how concrete behaves over time when loaded.
Name one factor that can influence shrinkage in concrete.
Consider what happens with more water.
What is creep in concrete?
Consider how materials respond to prolonged weight.
True or False: Shrinkage only occurs when concrete is under load.
Think about what happens to concrete once it has hardened.
Given a scenario where a 20-storey building has shown deflections of 25mm over 5 years due to creep, calculate the average creep rate per year. What design changes could mitigate future issues?
Consider dividing the total deflection by the total duration.
Suppose a bridge segment experiences a shortening of 10mm due to both creep and shrinkage. If shrinkage is determined to be 6mm, what is the contribution of creep? Discuss how this can be addressed in future designs.
Think about how to isolate what part of the shortening is due to each factor.
