Abstract:

The fracture surfaces of both plain and fiber-reinforced mortar and concrete are analyzed using the scanning electron microscope SEM. Proper sample preparation techniques for SEM examination of mortar and concrete are discussed. Fracture surfaces of samples broken in splitting tensile, flexure, and compression tests are compared using SEM photomicrographs. Micromechanisms of failure are discussed for the different lists for samples cured 7, 14, 21, and 28 days.
