What is the edge crush test and why is it important

Jul 23, 2021 · The test measures the resistance of the edges to crushing, since it is the corners and edges of the boxes that are mostly responsible for bearing the loads. Therefore, performing an edge crush test means knowing the strength of the factor that contributes the most to a box's resistance.

Drainage Board Crushing at BasementWall and Slab Joint

I'm curious to know if there is a concern for drainage board crushing at the joint of a foundation wall and basement slab. This detail seems fairly reasonable as a way to mitigate water intrusion through basement walls, but many times the basement wall is relying on the concrete slab to resist lateral forces.

Compressive strength Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials
