HD 50 is a fast setting, fiber reinforced, latex-modified, heavy duty, one component concrete repair material requiring only water to mix and apply. HD 50 is a cement based compound having similar characteristics to normal portland cement mixes and is compatible with portland cement concrete.
Dayton Superior HD 50 is a rapid-setting, fiber-reinforced, latex-modified repair mortar designed for fast-turnaround concrete patching. This one-component, cement-based material delivers over 2,000 psi compressive strength in one hour and can be opened to traffic or coated in as little as 60 minutes. Engineered for horizontal, vertical, and overhead repairs, HD 50 is compatible with Portland cement concrete and meets ASTM C-928 standards for very rapid hardening cementitious repair materials.
