AB  - This study analyzes the feasibility of valorizing industrial by-product, fly ash from a
thermal power plant as a partial replacement of mineral filler-limestone for the production of
self-compacting concrete (SCC). Three types of SCC mixtures with different portions of fly
ash and the reference mixture with limestone were designed. The synthesized SCCs in the
fresh state were examined for density, entrained air content, flowability (Slump flow, Slump
flow time (t500), V-funnel time (tv)), passing ability (L-box), and segregation resistance,
while hardened state testing included: density, compressive and flexural strength, static
modulus of elasticity, water permeability, resistance against freezing in the presence of deicing salt, and SEM analysis. Taking into account the obtained results it can be concluded
that the addition of fly ash has a positive impact on the concrete properties and that the
optimal content of fly ash is 20 % with respect to the total filler mass

AB  - High-temperature materials are used in a wide range of industries and applications such as gas
turbine engines for aircrafts, power and nuclear power plants, different types of furnaces,
including blast furnaces, some fuel cells, industrial gas turbines, different types of reactors,
engines, electronic and lighting devices, and many others. Demands for high-temperature
materials are becoming more and more challenging every year. To perform efficiently,
effectively and at the same time to be economically viable, the materials used at high
temperatures must have certain characteristics that are particularly expected for applying
under such extreme conditions, for example, the strength and thermal resistance. In the
present review, some important requirements that should be satisfied by high temperature
materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics,
intermetallic alloys, and composites as four different categories of these materials, which are
also considered in respect to possibilities to overcome some of the current challenges.
AB  - U visokotemperaturske materijale spada široki spektar materijala koji se koriste u industriji, za primenu poput turbina za motore i avione, termo i nuklearne elektrane, različite tipove peći uključujući visoku peć, gorivne ćelije, turbine za različiite namene u industriji, razne vrste reaktora, motora, uređaja u elektronici i osvetljenju, kao i mnoge druge. Svake godine zahtevi za visokotemperaturske materijale postaju sve izazovniji. Da bi se ostvarila efikasnost i efektivnost, i da bi se istovremeno postigla ekonomska održivost, materijali koji se koriste na visokim temperaturama moraju zadovoljiti određene zahteve i imati svojstva koja se očekuju u tako ekspremnim uslovima, kao što su, na primer čvrstoća i otpornost na povišene temperature. U ovom preglednom radu razmatrani su neki od značajnih zahteva koji moraju biti zadovoljeni
za visokotemperaturske materijale. Rad se odnosi na vatrostalne betone, keramiku, intermetalne legure i kompozite, kao četiri različite kategorije ove vrste materijala. Navedeni materijali su razmatrani u pogledu mogućnosti prevazilaženja nekih trenutnih izazova.

AB  - Stabilizacija teških metala, posebno bakra, iz kiselih otpadnih rudničkih voda izvodi se njihovom solidifikacijom u sumpor polimerni beton kao ekološki prihvatljiv građevinski materijal. Postupak se izvodi tako što se u reakcionom sudu agregat u količini od 56 mas. % zagreva na 160 °C. Zatim se dodaje 5 mas. % letećegpepela iz termoelektrane kao filera i 6 mas. % peleta letećeg pepela sa adsorbovanim teškim metalima iz rudničkih voda. Homogenizovanoj čvrstoj mešavini dodaje se 33 mas. % rastopa elementarnog i modifikovanog sumpora, tzv. sumpor modifikovanog veziva u masenom odnosu 98,2 % elementarnog sumpora i 1,8 % modifikovanog sumpora. Modifikovani sumpor dobijen je mešanjem elementarnog sumpora kao nus-proizvoda iz rafinacije nafte sa diciklopentadienom, na temperaturi od 132-141 °C. Nakon homogenizacije u trajanju od 2 do 5 minuta, dobijena mešavina izliva se u kalupe prethodno zagrejane na 120 °C i vibrira 10 sekundi. Površina ovako dobijene sumpor polimerne betonske mešavine se izravna i ostavi da očvrsne u kalupu na sobnoj temperaturi. Nakon 3 časa očvršćavanja uzorci se vade iz kalupa i neguju na sobnoj temperaturi tokom 24 časa. Dobijeni materijal je nakon ispitivanja pokazao zadovoljavajuće karakteristike potrebne za sve oblasti primene konvencionalnih betona. Ovim postupkom eliminisani su teški metali iz otpadnih rudničkih voda, korišćeni su industrijski nus-proizvodi (leteći pepeo i sumpor), čime su smanjene njihove deponije dok dobijeni materijal ne dovodi do sekundarnog zagađenja životne i stoga se smatra ekološki prihvatljivim.
AB  - Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried out by heating the aggregate in an amount of 56 mass % in a reaction vessel with continuous mixing up to a temperature of 160 °C. Subsequently 5 mass % of fly ash from the thermal power plant is added as a filler and 6 mass % of fly ash pellets with absorbed heavy metals from mine waters. Finally, 33 mass % of the sulfur modified binder, that is mixed melted elemental and modified sulfur in the mass ratio of 98.2 % : 1.8 % is added to the homogenized solid mixture. Modified sulfur is prepared by mixing the elemental sulfur that is by-product of oil refining with dicyclopentadiene at a temperature of 132-141 °C. After the homogenization of the sulfur polymer concrete mixture for 2-5 minutes, the resulting melted mixture is poured into the molds pre-heated to 120 °C and vibrated for 10 seconds. Thus obtained surface of the sulfur polymer concrete mixture is flattened and leave to harden in the mold at room temperature. The samples were removed from the mold after 3 hours of hardening and then cured at room temperature for another 24 hours. After characterization, obtained building material showed satisfactory properties required for all application areas of conventional concrete. By this process, heavy metals from mine wastewater were eliminated, industrial by-products (fly ash and sulfur) were used thus reducing their landfills, while the obtained material does not lead to secondary environmental pollution and therefore is considered as environmentally friendly.
