摘要
本文研究了水泥净浆在外力作用下产生电流的力电效应 ,以及由于电场作用产生变形的电力效应。通过实验测试了水泥净浆梁弯曲时产生的电流和在外加电场作用下的弯曲变形 ,表明所产生的电流从梁受压的一侧流出 ,电致弯曲的方向与施加电场的方向相反。提出了水泥净浆偶电层中离子分布模型 ,以此探讨水泥净浆力电。
Mechano electric effect and electromechanical effect were investigated in this paper.The measurement of stress induced electrical current and electrical field induced bending deformation ws done on cement beam.The induced electrical current was brought out form the compressed section of the beam.And the bending dirction of the beam led by electrical field was in contrast with the direction of electrical field.A model about the distribution of ions in double electrical layer of cement paste was used to explain the mechanism of mechano electric effect and electromechanical effect.
