碩士 === 國立中興大學 === 土木工程研究所 === 83 === Influence of packing structure of coarse aggregate on the dividing strength(FG) of Light-Weight aggregate concrete(LAC) were studied. In the study , the packing structure of coarse aggregate were varied by different gradations obtained from the change of maximum size of aggregate (Dmax) .Besides ,effects of the fraction of mortar on the FG were also investigated . Based on the analysis of the test results ,it was fistly assured about the exitence of FG ,which is intensively related to the packing structure of aggregate . The larger the selected Dmax is ,the greater the FG will be . Additionally ,an increase of fraction of mortar can enhance the FG value too .
