碩士 === 國立臺灣海洋大學 === 河海工程學系 === 106 === This study mainly studied the influence of cement-based composite materials on the properties of ggbs and sodium silicate as additive material. Use of cement and ggbs mixed proportion of mortar test body, and water glass 3%, 5% of the amount of test data, The analysis of compressive strength, water absorption rate, length variation, resistivity and rapid chlorine ion penetration test are effected by adding ggbs and water glass. Test results (1) When the amount of water glass added is increased without adding ggbs, the compressive strength is increased. When adding ggbs and water glass, the strength is improved only after 28 days. (2)Adding water glass will not reduce the water absorption rate. The water absorption rate is mainly caused by the addition of ggbs. (3) adding water glass to increase the shrinkage, and adding ggbs will make the shrinkage more obvious. (4) Adding ggbs and water glass can increase the resistivity of the test body, and also reflect the compactness of the test body. (5)The pure cement sample has a higher total charge passed than the test body to which ggbs or water glass is added. Represents the addition of ggbs or water glass can effectively reduce the total charge passed.
