The Concrete Countertop Institute has teamed with Advanced Cement Technologies to offer PowerPozz High Reactivity Metakaolin by the bag to concrete countertop fabricators and other decorative concrete contractors who need small quantities. Previously, metakaolin was available only in bulk, at a minimum in a pallet of 48 40-lb bags. This is enough for approximately 77 to 125 kitchens worth of concrete countertops. The Institute recommends that 10 percent to 20 percent of the cement in a concrete countertop mix be replaced by metakaolin. This increases the compressive strength, density and workability, and decreases efflorescence and alkali-silica reaction. Metakaolin can interfere with acid stain reaction, however, so contractors should use caution when planning to create a countertop with an acid-stained look.
