Horizontal Standardization and Harmonization of Leaching Test Methods for Waste, Secondary Raw Materials, Construction Materials and (contaminated) Soil
In recent years, a lot of work has been carried out in evaluating environmental impact from a wide variety of materials in a wide range of different applications. The continously recurring inability to compare results between different jurisdictions and between disciplines can be resolved by focusing on a limited number of key test methods. This does require the recognition that many existing t...
متن کاملUtilization of Soil Stabilization with Cement and Copper Slag as Subgrade Materials in Road Embankment Construction
In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...
متن کاملconstruction wastes as raw materials for geopolymer binders
it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...
متن کاملUtilisation of aggregate materials in road construction and bulk fill
In the UK, at present, the majority of aggregate materials, for all construction applications, are obtained from primary resources such as crushed rock and sand and gravel. Material extraction results in many adverse environmental impacts and utilisation consumes a finite natural resource. In the UK we also produce large quantities of waste and by-product materials, from industrial and domestic...
متن کاملValorization of Phosphorus Secondary Raw Materials by Acidithiobacillus ferrooxidans.
This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L) and two doses (2 and 4 g/L) of phosphorite...
