| Summary: | 碩士 === 國立臺灣海洋大學 === 河海工程學系 === 96 === In this study, addition of lithium compounds to restrain the alkali-silica-aggregate reaction (ASAR) of concrete. Various lithium compounds were added, and the expansion percentage, compressive strength, bending strength and tensile strength are examined to see the efficiency of the lithium compounds on retraining the ASAR.
Results show that adding lithium compounds can restrain the ASAR and lower the expansion percentage. Increasing amounts of lithium compounds can decrease the effects of ASAR. For mechanical properties, the results depend on what kind of lithium compounds we use as well as what kind of the mechanical properties we are interested in. The results showed that adding adequate amount of lithium carbonate or lithium hydroxide can enhance the bending strengths. No significant trend can be found for the tensile strength. For compressive strength, as the amount of lithium carbonate or lithium hydroxide increased the value decreased.
