Advanced Cement Technologies GB-HRM is a manufactured pozzolanic mineral admixture which significantly enhances many performance characteristics of cement-based mortars, concretes and related products.

GB-HMR, 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 contribute to: Increased strength, reduced permeability, greater durability and effective control of 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. Conforms to ASTM C-618, Class N Specifications for Natural and Calcined Pozzolans.
