14 Characteristics of Bamboo Wood - Simplicable

Sep 15, 2018 · Compressive Strength Compressive strength is the ability of a material to resist forces that are trying to crush it. Generally speaking, bamboo has a higher compressive strength than wood, brick or concrete. The actual compressive strength of bamboo depends on the species, size and part of the plant with fibers at the top section of the plant being closely packed and stronger.

Uniaxial Compressive Strength - an overview ...

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...
