논문 초록 (Abstract)

Recently ultra high-storied buildings are built variously as experiment result, the buildings increase to improve durability and economic feasibility. Development and research of compound ashes for high efficiency concrete swaddling clothes security are consisting as many-sided in these advantage point. meta kaolin is receiving rem newly as principal parts compound ashes, which is Profitable environment conservation enemy been coming to the fore socially with economical aspect displaying durability and strength of level such as present. Therefore, execute an experiment to analyze effect of the replacement ratio that get flowing and mechanical properties of mortar. according execute the replacement ratio of meta kaolin and silica hume by 0, 15, 30, 45%. Experiment result Liquidity effect of Meta kaolin mortar displayed tendency that fall decline in the metathesis rate since in case it is the metathesis rate 15%, and tensile strength showed tendency such as compression strength according as the metathesis rate increases, and the air amount decreased greatly according as the metathesis rate increases. In the case of compression strength, show tendency until metathesis rate 30%, and fell in case of something wrong. All tensile strength and flexural strength showed tendency such as compression strength. Liquidity of mortar of Silica fume displayed tendency that flow performance increases more or less preferably until metathesis rate 15% and the air amount shows resemblant tendency with meta kaolin.In the case of compression strength display most strength revelation and strength.
