碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 94 / This research targets Metakaolin as main material, with various kinds of combination materials and binder, and uses a mechanism to make colding metakaolin lightweight aggregate and then makes five different proportion of metakaolin lightweight aggregate, with an aim to know the effects of different proportion on aggregate through the destruction of point load , sift analysis , and unit weight. Choosing suitable aggregate based on ACI norm to set three groups of different water-cement ratio A(0.54)、B(0.46)、C(0.35) to mix into lightweight aggregate concrete, this is to find out the correlation between physical properties and mechanical behavior of metakaolin lightweight aggregate concrete through pressure resistance , splitting off , absorption capacities. The result shows that different proportions of metakaolin lightweight aggregate also take different effects, a suitable formula is selected in accordance with the application. Of all the groups, group D (cement：slaked lime：metakaolin：fly ash：sand =12.5%：12.5%：28.125%： 9.375%：37.5%) has the best mechanical and physical performance. The mechanical properties such as pressure resistance and splitting strength of aggregate made from metakaolin lightweight aggregate concrete can meet up with CNS and ASTM norms, and it is superior to fly ash lightweight aggregate concrete.
