Properties of composite cement with commercial and manufactured metakaolin
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin (MK), manufactured by thermal activation/calcination of domestic kaolin clay, and commercial matakaolin ...
Prevention of electrofilter ash toxic leaching by embedding in composite materials
(Inženjersko društvo za koroziju, Beograd, 2013)
Disposal of the fly ash may pose a significant risk to the environment due to the leaching of hazardous pollutants. The only sustainable solution for the pollution-prevention is the reapplication of fly ash as one of the ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Vulkaniti Stolova kao građevinski kamen / Volcanic rocks of Mt. Stolovi as a building stone
(Savez inženjera i tehničara Srbije, Beograd, 2013)
Vulkaniti Stolova južno od Kraljeva predstavljeni su malim vulkanitskim telima dacito-andezita. Ovi vulkaniti su od otvaranja kamenoloma Kamenica pored reke Ribnice korišćeni za dobijanje kocke, agregata i ploča za oblaganje. ...
