Grade: Calcined Grades

Product: Metax-RX

High-reactivity metakaolin is a highly processed reactive aluminosilicate pozzolan, a finely divided material that reacts with slaked lime at ordinary temperature and in the presence of moisture to form a strong, slow-hardening cement. It is formed by calcining purified kaolinite, generally between 6500-7000C in an extremely fired rotary kiln. It helps for acceleration in the hydration of ordinary Portland cement and its major effect can be seen within 24 Hours. It reduces deterioration of concrete by ‘Alkali Silica Reaction’. The product is considered to have twice the reactivity of most other pozzolans & replaces 8-20% Portland cement by weight.

Use of product offers following benefits:-

• Increased compressive & flexural strengths.
• Reduced Permeability.
• Reduced potential for Efflorescence.
• Increased resistance to chemical attack.
• Increased durability.
• Reduced effect of ASR.
• Reduced shrinkage.
