Piezoelectric effect of hardened cement paste
AbstractThe piezoelectric effect of hardened cement paste was studied in this paper. As compressive stress was applied on the specimen, an electrical current was observed. The electrical current increases nonlinearly with compressive stress. The average sensitivity constant reached is 1.0×10−8 A/MPa. Through investigation of the variation of piezoelectric effect with absorbed water content in specimens, the mechanism of this phenomenon was analyzed. Piezoelectric effect of hardened cement paste is related to the transportation of mobile ions along with water in the hydrated cement product under stress.
