Transport and storage of heavy metals in the Sava River Basin in Serbia
(Srpsko hemijsko društvo, Beograd, 2014)
Selected heavy metals (Cu, Zn, Pb and Cd) in the water and sediment of the Sava River in Serbia were investigated from three locations in the vicinity of industrial and urban settlements (Sabac, Obrenovac and Belgrade) ...
Comparison of refractory coatings based on talc, cordierite, zircon and mullite fillers for lost-foam casting
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2015)
This study presents the results of an investigation of high-temperature materials refractory coatings based on different refractory fillers including talc, cordierite, zircon and mullite applied in the lost-foam casting ...
Need to Improve the Natural Aggregate Resources Supply in the City of Belgrade (Serbia)
(Berg Fac Technical Univ Kosice, Kosice, 2016)
The City of Belgrade is the largest market for aggregates in Serbia but the production of natural aggregates is rather small, around five percent of total consumption. This reflects the geology of the City of Belgrade ...
Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis
(Savez hemijskih inženjera, Beograd, 2010)
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. ...
