High reactivity metakaolin (HRM) is an ultrafine pozzolan that enhances the strength, durability, workability and appearance of Portland cement based products and concrete. Unlike most pozzolanic materials, metakaolin is a bright white powder manufactured under strict quality control that ensures consistent high reactivity. The pozzolanic properties of metakaolin yield superior strength and durability while simultaneously protecting against chemical attack, including efflorescence and alkali-silica reaction (ASR).
