  • The self-healing performance of cement mortar specimens at different ages and temperatures was tested by compressive strength repair rate, crack repair rate, and electrochemical impedance spectroscopy (EIS), and then was analyzed using the scanning electronic microscope (SEM) to study the microscopic self-healing mechanism of magnesium acrylate cement-based materials. The test results showed that the effect of magnesium acrylate on the compressive strength repair and apparent repair of the mortar specimens was not obvious at the early age. The effect on compressive strength repair intensifies gradually with the increasing age, and the apparent crack repair rate at 7 d reached 100.0%. Meanwhile, medium-high temperature was beneficial to self-healing effect, but the effect above 40 ℃ was no longer significant. EIS showed that the equivalent circuit parameters of the test group at the age of 28 d were better than those of the control group; the repair effect of the magnesium acrylate at old age is significantly better than the "healing" effect brought by the hydration reaction of cement-based materials.
