查询词典 concrete

When mixed into the same carbon fiber quantity is 1.0%, differ age material's AC impedance chart is discrepancy very much, along with to hydrate age's add, C-S-H gel isa great deal of form, the solution resistance at the concrete is gradually aggrandizement, the carbon fibre of here qua transmit electricity quality disperse would leading effect of conductance, along with the add of exterior load, the transmit electricity quality of concrete is almost nothing change, till breakage, resistance change rate tempestuousness add, and that the resistance change rate along with inside stress linearity add of corbon fibre concrete in elasticity phase, when near peak value load, resistance rate just gradually add, indicate the test sample would be about to breakage.

当碳纤维体积掺量同为1.0%时，不同龄期材料的交流阻抗谱相差很大，随着水化龄期的增长，C-S-H凝胶大量形成，水泥基材料中的溶液电阻逐渐增大，此时作为导电性分散相的碳纤维将起电导的主导作用。随着外部荷载的增加，基准水泥基材料的导电性几乎无变化，直到破坏时，电阻变化率剧烈增大，而碳纤维水泥基材料在弹性阶段其电阻变化率随内部应力线性增加，当接近峰值荷载时，电阻率才逐渐增大，预示试件即将破坏。
