Description
HRMK® 100 is a highly processed aluminosilicate pozzolanic mineral derived from the clay mineral kaolinite. It dramatically improves the overall durability of concrete, primarily by reducing permeability and increasing compressive and flexural strengths. This product conforms to ASTM C618, Class N Specifications for Natural and Calcined Pozzolans. Highly refined kaolin clay is calcined in a vertically oriented multiple hearth furnace.
The material is moved by mechanical rakes across each hearth and then drops to the next hearth below. Each hearth has separate temperature controls and, unlike with rotary kilns, the time that the material is inside the furnace and the temperature gradient that the material is exposed to is precisely controlled ensuring the consistent production of high-purity highly-reactive metakaolin. HRMK 100 admixture has a specific gravity of 2.6.
