In this study,fly ash and metakaolin were used as main materials,kalium hydroxide as activator,liquid sodium hydroxide as structural template to prepare geopolymer.

Geopolymer was synthesized with metakaolin and tungsten-tailing as the main raw material and alkali activator composed of sodium silicate solution and sodium hydroxide solution.

Researches show that,the Metakaolin of Datong coal gangue made from temperature 600℃,possesses best pozzolanic activity;Concrete compression strength of blending Datong metakaolin of 600℃ has surpassed calcined meta kaolin compression strength of 850℃ and 1000℃,and at the moment its nature is optimum.

Preparation and characterization of kaolin-suported TiO_2 photocatalyst;

Studying of scale buildup mechanism of triple compound flooding──Interaction sodium hydroxide with kaolin and montmorillonite;

By means of rock testing such as X-ray diffraction analyzer and XL-30 energy spectrum electron microscope, chemical behavior of kaolin in 7 different types of acid, i.

Preparation and possible mechanism of potassium acetate/metakaolinite intercalated composites

A geopolymer material based on dehydrolyed aluminosilicate and phosphoric acid was synthesized from metakaolinite condensed with low-polymeric \~(3n-)_n tetrahedral units in phosphoric acid aqueous solution at room temperature.

The degree of geopolymeric reaction between metakaolinite and sodium silicate solutions was characterized by the compressive strengths of the products of the geopolymeric reaction.
