Application of fly ash to reduce soil dispersivity in embankments
(Publ House Bulgarian Acad Sci, Sofia, 2021)
Due to rapid development of modern highways and railroad in Serbia, the need for embankment materials has increased. Deposits of natural materials used for this purpose often contain dispersive soils. On the other hand, ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier, 2022)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessary
when existing prestressing wires are damaged or after a certain period of time. The objective of this
paper is to describe the ...
Structure and properties of ZnO/ZnMn2O4 composite obtained by thermal decomposition of terephthalate precursor
(Journal of the Serbian Chemical Society - JSCS, 2022)
A biphasic [Mn(dipya)(H2O)4](tpht)/{[Zn(dipya)(tpht)]·H2O}n complex material, I, (dipya = 2,2’-dipyridylamine, tpht2– = dianion of terephthalatic acid) was synthesized by ligand exchange reaction and characterized by XRPD ...
Raw kaolinitic–illitic clays as high‑mechanical‑performance hydraulically pressed refractories
(Journal of Thermal Analysis and Calorimetry, 2022)
The usage possibility of 19 composites of raw refractory clays from Serbia containing approximately 53.29% of SiO2 and 26.73% of Al2O3 is presented. The sum of fluxing oxides was 57.74%, while these materials contained 32% ...

Institut IMS ima lidersku poziciju među multidisciplinar-nim naučno-istraživačkim organizacijama u Srbiji i regionu. Visoko je pozicioniran u oblasti građevinarstva i inženjer-stva. IMS poseduje jedinstveni spoj ...
Imobilizacija teških metalnih jona Zn2+, Ni2+, Pb2+ i Cu2+ u strukturi materijala na bazi cementa / Immobilization of heavy metal ions Zn2+, Ni2+, Pb2+ and Cu2+ in the structure of cement-based materials
(Inženjersko društvo za koroziju, Beograd, 2020)
Prirodni zeolit i bentonit korišćeni su kao mineralni dodaci u mešavinskom dizajnu ekološki sigurnih građevinskih materijala na bazi cementa. Ispitane su adsorptivne sposobnosti ove dve glinene sirovine, tj. njihov afinitet ...
Metodologija pregleda i ocena stanja konstrukcije izložbenih hala Beogradskog sajma
(Integritet i vek konstrukcija, specijalno izdanje, 2023)
Beogradski sajam predstavlja jedno od najuspelijih ostva-renja domaće arhitekture i građevinskog konstrukterstva. Sagrađen je između 1954. i 1957. godine, prema arhitek-tonsko-urbanističkom rešenju Milorada Pantovića i ...
