ChemSpeed™ 75
ChemSpeed 75 is a single component, very rapid setting high performance structural repair mortar with added migrating corrosion inhibitor. This state of the art fly ash formula produces high, early strength at a wide range of temperatures with very low permeability. Areas repaired with ChemSpeed 75 can be returned to rubber wheeled traffic within 2 hours depending on temperature. ChemSpeed 75 meets ASTM C928 for rapid repair of concrete and can be extended up to 60% with silica gravel deep placements.
