中文摘要 | 本研究為能探究HPC的耐久程度,將各種滲透性試驗方法作詳盡的評估,以有效的求得HPC高耐久性低滲透性的品質指標。結果顯示,表面透水法較達西定理之透水試驗快速簡易,然卻未考慮透水路徑長度;可藉由多種通電方法包括電滲法、直流電場下的氯離子滲透法及交流電參數法等作比較評估。結果顯示以直流電阻量測法及交流電滲法可改善現階段常使用之氯離子滲透法等電滲法,縮短時間,又可避免極化問題及溶液溫度升高之影響等缺點,為未來值得推廣作為HPC滲透量測方法。 |
英文摘要 | In this research the durability of HPC is mainly studied, so various permeability test methods are assessed in details in order to obtain the meaningful quality aim of HPC with high durability and low permeability. Research results indicate that the surface permeating method reacts faster and is more easy to manipulate than the permeating test based on the Darcy’s law, but ignore the length of the permeating path. Furthermore, chloride penetration current and alternative current are conducted to compare with and to do the assessment. Especially, the method by using alternative current is better than the present chloride penetration method because the test time is decreased, the polar problem and the temperature creasing may be avoided. Therefore, the alternative current coefficient method is worth being promoted for the measurement on HPC penetration. |
