International Journal of Electrochemical Science, 2020 One of the techniques to improve the concrete durability is to use cement materials blended with silica fume, slag and fly ash. The use of calcined clay cement in the metakaolin form as a pozzolan for mortar and concrete has received remarkable interest ...

Monitoring of historical structural materials with computed tomography
Structural Concrete, EarlyView.Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Crystallization behavior of zeolite beta from acid-leached metakaolin
, 2010 Well-crystallized zeolite beta was synthesized by using acid-leached metakaolin as the silica-alumina source and tetraethylammonium hydroxide structure-directing agent. The influence of the composition of the reaction mixture on product crystallinity was

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures
Structural Concrete, EarlyView.Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.

Metakaolin as an Additive in Composite Cement [PDF]
, 2012 Metakaolin made from kaolin is used around the world but rarely in Vietnam where abundant deposits of kaolin is found. The first studies of producing metakaolin were conducted with high quality Vietnamese kaolins.
