    摘要: A process for making a pervious concrete comprising a geopolymerized pozzolanic ash. Generally, the process includes mixing a solid aggregate and a geopolymerized pozzolanic ash binder together to form a pervious concrete mixture. Some examples of suitable aggregates comprise recycled carpet, recycled cement, and aggregates of coal-combustion byproducts. The geopolymerized pozzolanic ash binder is made by combining a pozzolanic ash, such as fly ash, with a sufficient amount of an alkaline activator and water to initiate a geopolymerization reaction. The activator solution may contain an alkali metal hydroxide, carbonate, silicate, aluminate, or mixtures thereof. In some aspects, the final concrete forms a solid mass in the form of pavement or a pre-cast concrete shape. The solid mass of concrete may have a void content of between about 5% and about 35%.
