Trabecular bone examples
SpletCalcium carbonate, by comparison, has a rather low compressive strength, but is still able to find good use in concrete in the form of “whiskers” [56], needle-like single crystals of calcium carbonate that improve compressive, tensile, and flexural strength [57], akin to the mechanical advantages offered by trabecular bone [58,59]. SpletMarrow-free trabecular bones from dog, man, monkey, and steer were obtained by use of a special marrowwashing technique. The quantities of the various trabecular bone fractions (water, organic, volatile inorganic, and nonvolatile inorganic (ash)) found in these animals were compared with those of cortical bone.
