Electrical emission in mortar under low compressive loading
Electrical emission in mortar under low compressive loading was investigated in this paper. Electrical emission in mortar is apparent even under the compressive stress less than 30% of compressive strength. Under uniaxial trapezoid load, there are two sinesoids associated with the loading and unloading phases, respectively. With the loading rate increasing, the amplitude of electrical emission increases. The mechanisms of the electrical emission in mortar under low compressive stress include the opening of microcrack, the flow of liquid in mortar, and the charge leakage. The electrical emission under cyclic loading was also studied. An understanding of the electrical emissions may lead to practical applications such as the nondestructive testing of concrete.
