Abstract
Disclosed are wax emulsion modifiers for concrete and cement formulations and methods for preparing same. The modifiers are applicable to pervious concrete, used in residential areas, parking lots and parks to more effectively manage storm waters and improve environmental practices. This invention also relates to conventional Portland cement concrete mix designs with little to no sand, which provide improved workability, low hydration rates without sacrificing strength while achieving high levels of porosity for water transmission.
