Absorption characteristics of metakaolin concrete
Cement and Concrete Research, 2004 Abstract The water absorption (WA) by total immersion and by capillary rise of concrete containing metakaolin (MK) is investigated. Cement was partially replaced with up to 20% MK. The results show that the presence of MK is greatly beneficial in reducing the WA by capillary action.

Metakaolin as a cement extender [PDF]
, 1996 The effect of 10% and 20% replacement metakaolin on a number of aspects of hydration chemistry and service performance of ordinary Portland cement pastes has been investigated. The analysis of expressed pore solutions has revealed that metakaolin-blended specimen pastes possess enhanced chloride binding capacities and reduced pore solution pH values ...

Metakaolin: nova generacija dopunskih cementnih materijala
, 2005 Metakaolin (MK) je termički aktiviran alumino-silikatni materijal visoke pucolanske aktivnosti. Dodatkom mata-kaolina cementu poboljšava se kvalitet koji se manifestuje kroz: povećanje čvrstoće, skraćenje vremena vezivanja (da li je ova karakteristka prednost ili ne zavisi od primene cementa) sniženje autogenog skupljanja, kontrolu alkalno-silikatne ...
