초록
The use of high-performance concrete (HPC) that incorporates various mineral admixtures has been increasing worldwide. Metakaolin (MK), one of these mineral admixtures, is the most recent mineral admixture to be commercially introduced to the concrete construction industry. However, MK has not been used well in the construction field in Korea because it is fabricated only at the laboratory scale to test its use. Moreover, its use in commercial products fabricated in real plants in Korea has not been clearly verified yet. Therefore, in this study, the properties of mortar, that includes various mineral admixtures such as silica fume and MK, as a partial cement replacement were investigated in terms of workability and compressive strength to estimate the feasibility of MK fabricated in a real plant, by using Korean kaolin.
