A Study on the Strength Properties of Concrete Containing Meta-Kaolin

메타카올린을 사용한 콘크리트의 강도특성에 관한 연구

This study was performed to investigate the flow behavior of fresh concrete. strength properties, and durability properties on the chloride penetration resistance of hardened concrete containing Meta-Kaolin(MK) in the range from common strength to high strength to facilitate the use. The results are compared with properties of concrete containing Si1ca Fume(SF). As a result. superplasticizer required in MK concrete was decreased by 8-28% compared to SF concrete with the same slump, but MK concrete became more sticky than SF concrete. It was also found that considering the strength, the optimal cement replacement ratio of MK was 15%, and MK had concrete durable and dense by decreasing the average pore diameter of concrete.
