X-ray diffraction and SEM analysis of waste sulfur modification for use in concretes
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2021)
Secondary sulfur obtained as a by-product in the oil refining process is a major problem as an environmental pollutant. One of the possibilities of environmental protection is the use of sulfur obtained in this way as a ...
Transformations of mechanochemical activated Na2CO3
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2022)
During mechanical activation, energy of treated material is increase to a higher level. This can lead to chemical transformation of the activated material. This is the point where we can talk about mechanochemical ...
XRD analysis of activated four-component ceramics
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2021)
The aim of the presented research was to analyze ceramic material based on cordierite as a function of activation time and sintering temperature. Three-component oxide mixture was prepared (MgO + Al2O3 + SiO2 in the ratio ...
