Supercritical flow in circular conduit bends
(Taylor and Francis Ltd., 2015)
A complex flow pattern occurring in a circular conduit bend with supercritical flow has been studied. The main objective was to obtain reliable criteria for prediction of the onset of helical and choking flow, in order to ...
Hydraulic Jumps in Adverse-Slope Stilling Basins for Stepped Spillways
(MDPI AG, 2018)
The performance of flat stilling basins can be inadequate for conditions when the tailwater depth is insufficient for hydraulic jump stabilization. In such cases, adverse-slope stilling basins can be used because they ...
Radiological and material characterization of high volume fly ash concrete
(Journal of Environmental Radioactivity, 2016)
The main goal of research presented in this paper was the material and radiological characterization of high volume fly ash concrete (HVFAC) in terms of determination of natural radionuclide content and radon emanation and ...
Daylight utilization potentials of highly glazed individual office spaces in Belgrade climate condition
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Office buildings have high standards for lighting requirements, which greatly contribute to high lighting energy consumption. Daylight utilization is one of the means to reduce it. The goal of this paper is to evaluate ...
Alkali-activated concrete with Serbian fly ash and its radiological impact
(Elsevier, 2016)
The present paper reports the results of a study on different types of fly ash from Serbian coal burning power plants and their potential use as a binder in alkali-activated concrete (AAC) depending on their radiological ...
Towards a codified design of recycled aggregate concrete structures: background for the new fib Model Code 2020 and Eurocode 2
(Wiley-Blackwell, 2020)
The use of recycled aggregate (RA) to produce recycled aggregate concrete (RAC) is a proven way of decreasing the consumption of natural aggregate (NA) and landfilling of construction and demolition waste. However, adoption ...
Shaft spillway with deflector downstream of vertical bend
(Thomas Telford Services Ltd, 2014)
This study considers the hydraulic design of a shaft spillway with a constriction at the upstream end of the vertical bend. The effect of key factors relating to the capacity of the crest, shaft and tunnel is assessed using ...
Report of RILEM TC 281-CCC: outcomes of a round robin on the resistance to accelerated carbonation of Portland, Portland-fly ash and blast-furnace blended cements
(Springer, 2022)
Many (inter)national standards exist to evaluate the resistance of mortar and concrete to carbonation. When a carbonation coefficient is used for performance comparison of mixtures or service life prediction, the applied ...
Shrinkage of recycled aggregate concrete: experimental database and application of fib Model Code 2010
(Springer Netherlands, 2018)
This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC). The study aims at providing an analytic expression for the shrinkage strain of RAC to be ...
Mechanical and time-dependent properties of high-volume fly ash concrete for structural use
(ICE Publishing, 2016)
A two-phase experimental study on the effect of simultaneous partial replacement of cement and fine aggregate with fly ash on the mechanical and time-dependent properties of high-volume fly ash concrete (HVFAC) is presented. ...
