The effect of partial replacement of natural filler by ground waste sulfur originated from the oil refining process on fresh and hardened properties of self-compacting concrete was investigated. Properties investigated were slump flow, V-funnel, L-box, and sieve segregation of fresh concrete mixes; and compressive, flexural, and bond (pull off) str...

In this paper, the adsorption properties of two metallurgical wastes (slag and anode dust) and two municipal wastes (eggshells and coffee grounds) were described. Acetic acid was used as the adsorbate Adsorption kinetic was monitored during the adsorption process. The obtained results showed that all tested waste materials can be used as potential ...

Stainless steel X8CrNiS18-9 (standard EN 10088-3: 2005) is the most commonly used austenitic stainless steel due to its good machinability. This steel has high mechanical and working properties thanks to a complex alloying, primarily with the elements such as chromium and nickel. The content of sulphur present in the steel from 0.15 to 0.35% improv...

Aluminium and its alloys have excellent corrosion resistance. When aluminium is exposed to the atmosphere, a thin invisible oxide Al2O3 is formed, protecting the metal from further oxidation. Compared to pure metals, alloys can have higher corrosion resistance depending on the content of certain alloying elements. Various substances such as organic...
