Properties of Metakaolin blended cements
Advanced Cement Based Materials, 1994Abstract Metakaolin is a supplementary cementitious material with pozzolanic properties. Its activation by triacalcium silicate (C3S), triacalcium aluminate (C3A), and ordinary Portland cement is reported. The early hydration period of pastes containing metakaolin was investigated using isothermal calorimetry and conductivity.

Sulphate Resistance of Metakaolin Mortar
Cement and Concrete Research, 1998Abstract The partial substitution of cement (both high C3A and intermediate C3A) with metakaolin (MK) is investigated in terms of resistance of MK mortar to sodium sulphate (Na2SO4) solution. Results on strength, porosity, pore size distribution, and calcium hydroxide (CH) contents are also reported.

Metakaolin as supplementary cementitious material
Journal of Thermal Analysis and Calorimetry, 2005In this paper the optimization of the kaolin calcination is studied, aiming at using the produced metakaolin as supplementary cementitious material. Representative samples of poor Greek kaolin (Milos island) and a high purity commercial kaolin were tested. Samples were heated at different temperatures during different times.

Metakaolin (MK) je danes dobro poznan pocolanski material in se uporablja v gradivih na podlagi cementa, npr. malta in beton. Reakcija MK s kalcijevim hidroksidom ustvari cementne proizvode: kalcijev silikatni hidrat (CSH), stratlingit (C2ASH8) in tetra kalcij aluminijev hidrat (C4AH13) kot glavne faze, ki nastanejo pri temperaturi okolice ...

Impact strength of metakaolin ferrocement
Materials and Structures, 2014In this study, the impact performance of ferrocement with metakaolin was investigated to explore potential uses of both ferrocement and metakaolin in construction industry. A series of ferrocement specimens were cast with varying number of mesh layers and with varying metakaolin percentages. The specimens were normal water-cured for 180 days.

Flexural strength of metakaolin ferrocement
Composites Part B: Engineering, 2013Abstract Flexural strength of metakaolin ferrocements was evaluated through laboratory investigation. Reference mortar with OPC of 43 grade and metakaolin mortars with 5–25% metakaolin replacement in the increments of 5% with cement were made. Constant water to cementitious ratio of 0.5 was maintained for all the mortars.

Metakaolin as a radon retardant from concrete
Radiation Protection Dosimetry, 2003Granite aggregates are known to be the radon source in concrete. Recently, metakaolin has been introduced as a partial substitution of Portland cement to produce high strength concrete. It can effectively reduce the porosity of both the matrix and the aggregate/paste transition zone, which suggests its ability to retard radon emission from concrete ...

Construction and Building Materials, 2019
Abstract The influences of rice husk ash (RHA) on the reaction kinetics, mechanical property, and microstructure of metakaolin-based geopolymer (MG) were investigated. Geopolymer pastes containing different contents of RHA were prepared by sodium silicate activation.
