Product Description

High Pozzolan Active Metakaolin

1. Benefits and Application

GB-HRM is a manufactured pozzolanic mineral admixture that significantly enhances many performance characteristics of cement-based mortars,concretes and related products.
GB-HRM, derived from purified kaolin clay, is a white, amorphous, alumino-silicate, which reacts aggressively with calcium hydroxide to form compounds with cementitious value. Used at 5-15% replacement of cement by weight, GB-HRM will be favorable for increasing strength and reduce permeability. Meanwhile, it will also effectively reduce efflorescence and degradations caused by alkali-silica reaction(ASR) in concrete.
Description: A white, manufactured,amorphous alumino-silicate with excellent physical,chemical and pozzolanic properties.Conform to ASTM C-618, Class N Specifications for Natural And Calcined Pozzolans.
