Phillipsite and Al-tobermorite mineral cements produced through low-temperature water-rock reactions in Roman marine concrete

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Novel cements: low energy, low carbon cements

Sustainability and the UK cement industry Traditional Portland cement-based concrete provides the foundation for the built environment. Buildings constructed appropriately and imaginatively from this material can and do exhibit an impressive array of properties [1] especially those that have been designed to optimise the thermal mass of concrete [2]. This type of concrete building is expected t...

Center for By-Products Utilization PROPERTIES OF CONCRETE PRODUCED FROM MULTI-COMPONENT BLENDED CEMENTS

This paper presents a study on the behavior of concrete produced from multi-component blended cements. These blends were prepared by blending 20 percent to 60 percent ASTM Type I cement with the combination of Class C fly ash and clean coal ash. Two percent to four percent sodium sulfate anhydrite was added to the blends as a chemical activator. Tests were conducted on the prepared concrete for...

Low-temperature reactions: Tunnelling in space.

active sites for the growth of the cylindrical branches. These nanocrystals were grown by adding a molecularly dissolved PFDMS solution into a poor solvent for PFDMS, and then aging the resulting precipitate. As the surfaces of the nanocrystals need to be available as seeds for growing cylindrical micelles, surfactants could not be used to regulate the formation and size of the nanocrystals. Th...
