Abstract:
... A considerable quantity of Callovo-Oxfordian (COx) argillite will be excavated due to deep geological radioactive waste disposal. Till now, there is no viable solution to make use of the excavated argillite. This paper investigates the possibility of producing alkali-activated materials based on argillite. The raw argillite is mainly composed of illite, smectite, muscovite and traces of kaolinite ...

Abstract:
... Minerals excavated during industrial activities are stored on the soil surface, exposed to weathering, which leads to the initial development of soil. Plants contribute to soil mineral weathering, mainly by producing acidic or complexing root exudates. In addition, many plants produce antioxidant compounds and phenolic substances that could also contribute to mineral transformation processes, but ...

Abstract:
... The kaolinite-group minerals kaolinite, dickite, nacrite, halloysite including its metaform and their associates allophane and imogolite are phyllosilicates characterized by a rather simple chemical composition of Si, Al, O, and H. These elements contribute for the most part to the built-up of the continental earth crust, which down to a depth of approx. 1.5km, consists of 75% of sedimentary rocks ...
