What is Metakaolin? Concrete

Metakaolin is a pozzolan, probably the most effective pozzolanic material for use in concrete. It is a product that is manufactured for use rather than a by-product and is formed when china clay, the mineral kaolin, is heated to a temperature between 600 and 800ºC. Its quality is controlled during manufacture, resulting in a much less variable

General description of metakaolin

Metakaolin is a valuable admixture for concrete and/or cement applications. Usually 8% 20% (by weight) of portland cement replaced by metakaolin. Such a concrete exhibits favorable engineering properties. The pozzolanic reaction starts soon and continues between 7 to 28 days.

The Mechanical Properties of the Concrete Using

Environmentally friendly and high performance concrete is very import for the applications in sewage and water treatment industry. Using mineral additives such as fly ash and silica fume has been proven to be an effective approach to improve concrete properties. This paper reports a study of the effect of using both polymer and metakaolin additives together on the mechanical and durability

Metakaolin Range Imerys

Metakaolin in Glass Fiber Reinforced Concrete (GFRC) GFRC is a combination of mineral components and glass fiber, obtained by a projection method. Glass fiber strengthens concrete properties and gives GFRC cohesion, flexural resistance and ductility. Normally with time, lime formation within the cement, leads to weaker connections between the cement matrix and the fibers that can no longer

Transport properties in metakaolin blended concrete

One of the approaches in improving the durability of concrete is to use blended cement materials such as fly ash, silica fume, slag and more recently, metakaolin. By changing the chemistry and microstructure of concrete, pozzolans reduce the capillary porosity of the cementitious system and make them less permeable to exterior chemical sources as well as reducing the internal chemical

metakaolin in concretes containing 5, 10 and 15% metakaolin. Concrete in which 15% cement was replaced by metakaolin had 28% more tensile strength than the reference concrete which contains metakaolin. On the other hand, Courard . et al. (2003) produced mortars with metakaolin using a replacement range of 5-20% and showed that mortars with metakaolin had lower flexural strength

Metakaolin Wikipedia

Concrete application. Considered to have twice the reactivity of most other pozzolans, metakaolin is a valuable admixture for concrete/cement applications. Replacing portland cement with 8–20% (by weight) metakaolin produces a concrete mix that exhibits favorable engineering properties, including: the filler effect, the acceleration of OPC hydration, and the pozzolanic reaction.
