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.
