4 cards from this section. Quick, good the night before a test.
What formula is used to calculate compressive strength?
Think about the relationship between load and area.
What units are typically used for flexural strength?
Recall the common units for measuring pressure.
What does compressive strength measure?
Think about what load a structure needs to support.
True or False: Flexural strength is only relevant for beams.
Consider other concrete applications like slabs.
A structural engineer must design a concrete beam that can hold a load of 50 kN. Based on experimental testing, the beam’s flexural strength is calculated as 5 N/mm². Compute the width and depth required if the span length is 2 m.
Think about rearranging the formula to find dimensions based on desired strength.
If a concrete cylinder is tested till failure and shows a split tensile strength of 1.5 N/mm², compute the maximum load applied if the diameter is 300 mm and length is 600 mm.
Apply the formula while solving for P.
