Detailed Description

Product Description High Reactivity Metakaolin has been successfully incorporated into applications for concrete and related products throughout North America and the international marketplace. The following sections will describe many of those applications and the benefits that were achieved through the use of High reactivity metakaolin. Meets Engineering Specifications for High Performance, High Strength, and Lightweight Concrete. Bridges (structural and non structural components) Pavement Overlays Water Supply and Marine Benefits Reduced Permeability Increased Strength and Durability Prevention of ASR Precast and Repetitive Concrete Products Precast Cast Stone Block, Brick, and Paving Stones Benefits Increased Strength and Durability Reduced Permeability and Efflorescence Improved color and Appearance Fibercement Products, Ferrocement, and Glass Fiber Reinforced Concrete Roofing Products Benefits Reduced Drying Shrinkage Reduced Overall Permeability Improved Strength and Toughness Dry Bagged Products Mortars Stuccos Repair Materials Pool Plaster Benefits Reduced Permeability and Efflorescence Improved Finishability, Color and Appearance Specialty Uses Blended Cements Oil Well Cementing Shotcrete Decorative Interior Concrete Fixtures Sculpture High Reactivity Metakaolin has proven itself to be a highly versatile and effective concrete additive. It has been, and will continue to be, an important component in the modern world of construction. 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.
