Chemometric analysis of the influence of mechanical activation on the mica quality parameters
(Elsevier Sci Ltd, Oxford, 2015)
The differences in the set of the process parameters measured before and after mica mechanical activation and their influence on the grain size distribution related characteristics have been studied. The modification of ...
Leteći pepeo kao neophodna sirovina za održivu proizvodnju građevinskih materijala / Fly ash as important component for sustainability of building materials manufacturing
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
Nagomilavanje otpada predstavlja jedan od velikih problema moderne civilizacije, kako sa komunalnog tako i sa ekološkog, tehnološkog, urbanističkog, građevinskog i energetskog stanovišta. Raspoloživi podaci o proizvodnji ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves
(Springer, New York, 2020)
This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, ...
Concrete paving blocks and flags made with crushed brick as aggregate
(Construction and Building Materials, 2012)
Demolition of old buildings in urban cores has produced a large amount of waste material. Since they are mostly masonry structures the largest part of the waste material is ceramic waste. Besides that, ceramic waste is ...
Influence of FSW parameters on formation quality and mechanical properties of Al 2024-T351 butt welded joints
(Elsevier, Amsterdam, 2013)
The influence of R/v ratio on joint quality in 2024-T351 aluminum alloy was studied. Specimens were subjected to friction stir welding with the rotation rates of 750, 950 and 1180 r/min and welding speed between 73 and 190 ...
Analytical modeling of activation procedure applied in alpha-alumina thermo-mechanical synthesis
(Elsevier Sci Ltd, Oxford, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the gamma to alpha phase transformation rate was investigated. The moderation in the alumina samples ...
Has the latest global financial crisis changed the way road public-private partnerships are funded? A comparison of Europe and Latin America
(Elsevier Sci Ltd, Oxford, 2020)
A financial/economic crisis may have an adverse effect on transport public-private partnerships (PPPs) as both traffic demand is negatively influenced, and governments are further under pressure. However, research on awarded ...
Određivanje preciznosti metoda ispitivanja mehaničkih karakteristika opekarskih proizvoda i crepova od gline uporednim ispitivanjem / Determining brick and roof tile mechanical characteristics testing accuracy: Comparative investigation
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
U okviru standarda SRPS ISO/IEC 17025:2006 - Opšti zahtevi za kompetentnost laboratorija za ispitivanje i laboratorija za etaloniranje, pod tačkom 5.9 postoji zahtev koji se odnosi na obezbeđenje poverenja u kvalitet ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
