Mechanical, Durability and Microstructure Analysis Overview of Concrete Made with Metakaolin (MTK)

Metakaolin (MTK) has received a lot of interest in the past two decades as supplemental cementitious ingredient. MTK is actively being utilized concrete and there large body literature on characteristics containing MTK. A rigorous evaluation use concrete, however, lacking, which required to better know its benefits, mechanisms, current progress. As result, objective this study deliver an overview concrete. The physical chemical MTK, well hydration, workability, mechanical qualities, hydration durability, microstructure analysis MTK-based are discussed. comparison findings diverse presented, some key recommendations. suggest that adding enhances certain characteristics, particularly capabilities, but decreases flowability. Improvement durability with was also observed but, for this, less information available. For optimal performance, right dosage crucial. typical ideal range between 10 20% by weight binder. Further research gaps into recommended.
