Metakaolin is the anhydrous calcined form of the clay mineral kaolinite. Rocks that are rich in kaolinite are known as china clay or kaolin, traditionally used in the manufacture of porcelain. The particle size of metakaolin is smaller than cement particles, but not as fine as silica fume.

Sikacrete® M-100 is highly reactive metakaolin pozzolan for portland cement concrete, grouts and mortars applications. Sikacrete® M-100 meets the chemical requirements of ASTM C-618, Class N pozzolan.

Aug 1, 2024 · Metakaolin is defined as an anhydrous calcined structure of the clay mineral kaolinite, used for centuries in the production of porcelain and more recently as a pozzolanic additive in concrete to improve resistance to chemical attack …

Metakaolin is an anhydrous aluminosilicate obtained by the thermal decomposition of kaolin, a naturally occurring clay containing kaolinite mineral [Al2Si2O5(OH)4] and trace amounts of quartz and other minerals.

In this article, highly reactive metakaolin properties, influence of metakaolin on fresh and hardened concrete properties, durability, and application of concrete containing highly reactive metakaolin will be explained briefly.

Feb 26, 2025 · Background. Metakaolin, a highly reactive pozzolanic material, has gained attention for its use in pre-cured geopolymer concrete due to its unique chemical and physical properties 1,2,3.Derived ...

Apr 1, 2013 · Kaolin converts to a pozzolan material named metakaolin (MK) after suitable thermal treatment. MK can be used in mortar and concrete to improve their properties. In addition, MK can be used as a source of cementing materials in alkali activation or geopolymer.

Jun 1, 2023 · Metakaolin (MK) is created by the calcination of kaolin (firing process) to increase its reactivity/pozzolanicity by increasing the amorphousity nature that plays an important role in the strength performance of AABs [19], [20].

Dec 9, 2017 · Metakaolin (MK) is known to be a highly pozzolanic material that can be used in concrete. MK is usually produced by heating kaolin-containing clays, within the temperature range of about 600–900 ℃. This chapter summarizes the utilization of metakaolin in relevant worldwide standards, mainly in Europe and North America.

Our metakaolin ranges, such as our Argical™ M and MetaStar™ series, provide a broad range of benefits when used in concrete, lime mortars and plasters. Metakaolin is manufactured through the calcination of high purity kaolin to form an amorphous pozzolanic white mineral additive for use in concrete and specialty binder-based products.
