| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 87 === The purpose of the experiment is to research the inhibiting effect of electrochemical technique applied on the ASR expansion of mortar bar.The main discussion is about the influence factors:the amount of alkali content,the combination type of electrobath,and the intensity of current density.
The results show that:when the combination type of electrobath is LiOH v.s Ca(OH)2 ,the amount of alkali content has no apparent influence on inhibiting effect.When the combination type of electrobath is LiOH v.s NaOH ,most inhibiting effect is to the mortar bar containing 3.0% alkalinity.To discuss the inhibiting effect of the combination type of electrobath,there is most inhibiting effect as the combination type of electrobath is LiOH v.s Ca(OH)2 and LiNO3 v.s Ca(OH)2 ,and there is worst inhibiting effect as the combination type of electrobath is LiOH v.s NaOH and LiNO3 v.s NaOH.The influence of the intensity of current density is depending on which type of electrobath combination.
