Previous concrete comprising a geopolymerized pozzolanic ash binder

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%.

Methods and apparatuses for sagd hydrocarbon production

A process for recovering hydrocarbons from an in situ formation. The process includes the steps of injecting steam though an injection well into an underground extraction chamber having a hydrocarbon extraction interface, warming the hydrocarbons at the extraction interface to cause the hydrocarbons to flow downwardly by gravity drainage and to release dissolved hydrocarbon gases and moving the hydrocarbon gases from the extraction interface to improve heat transfer from said steam to said interface. The last step is to recover liquids such as hydrocarbons and water through a production well. The invention provides adding a buoyancy modifying agent to the steam to cause the hydrocarbon gases to accumulate in the well in a preferred location. The preferred location is at the top of the chamber where the gases protect the top of the chamber from being extracted to the point of breakthrough.
