Synthesis of calcium carbide-derived carbon by mechanochemical reaction of calcium carbide with sulfur, iron sulfide and zinc oxide
In the present work, we report a novel design and preparation for the mechanochemical synthesis of calcium carbide-derived carbon (CaC2-CDC) at ambient temperature. Thermodynamic calculations confirmed the possibility of calcium carbide-derived carbon formation by the reaction of calcium carbide with sulfur, iron sulfide and zinc oxide at ambient temperature. The CDCs were synthesized by the ba...
متن کاملEffects of calcium carbide waste on soil bacteria and enzymes
The effects of calcium carbide waste on some groups of soil microorganisms and soil enzymes were studied using standard microbiological and biochemical techniques. Soil samples were collected from a vehicle maintenance area as well as from an adjacent farm land (control) during the dry and rainy seasons. The population of all the bacterial groups in the different seasons was affected adversely ...
متن کاملSolidification/stabilization of toxic metals in calcium aluminate cement matrices.
The ability of calcium aluminate cement (CAC) to encapsulate toxic metals (Pb, Zn and Cu) was assessed under two curing conditions. Changes in the consistency and in the setting time were found upon the addition of the nitrates of the target metals. Both Pb and Cu caused a delay in CAC hydration, while Zn accelerated the stiffening of the mortar. Compressive strengths of the metal-doped mortars...
متن کاملProperties of Chemically Combusted Calcium Carbide Residue and Its Influence on Cement Properties
Calcium carbide residue (CCR) is a waste by-product from acetylene gas production. The main component of CCR is Ca(OH)₂, which can react with siliceous materials through pozzolanic reactions, resulting in a product similar to those obtained from the cement hydration process. Thus, it is possible to use CCR as a substitute for Portland cement in concrete. In this research, we synthesized CCR and...
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...
