2 cards from this section. Quick, good the night before a test.
What is the maximum pressure exerted by fresh concrete found?
Consider where the concrete is heaviest.
Name one factor that can affect the pressure exerted by fresh concrete.
Think about what could change as concrete is poured.
What type of behavior does fresh concrete display when poured?
Think about how it moves.
True or False: Lateral pressure is highest at the top of the fresh concrete placement.
Remember where the weight is concentrated.
If the height of a concrete placement is doubled, how does this impact the pressure at the base? Calculate the new pressure knowing the original height was 2m with a density of 2400 kg/m³.
Consider how pressure relates directly to height.
Discuss a method to mitigate excessive lateral pressure from fresh concrete on formwork. How can simple changes in placement improve safety?
Think about how you can control the movement.
