Fly Ash (FA) from a power station in South Africa was investigated to neutralise and remove contaminants from Acid Mine Drainage (AMD). After this primary treatment the insoluble FA residue namely solid residue (SR) was investigated as a suitable mine backfill material by means of strength testing. Moreover, SR was used to synthesise zeolite-P using a two-step synthesis procedure. Furthermore, ...
The use of natural aggregates with suitable characteristics for road construction presents in some regions a real problem availability or cost related to transport. However, the resources place, which are naturally unusable, can be used after treatment Hydraulic Road Binders (HRB). In this study, we propose valorize mineral Coal Bottom Ash (CBA), residue from combustion SONICHAR power station N...
We studied the host selection behavior and feeding preference of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). A. planipennis is an exotic forest insect pest native to Asia that was discovered in North America in 2002 and is causing widespread mortality of ash trees (Fraxinus spp.) in southeast Michigan and surrounding states.
