Structural Integrity Assessment of Welded Pressure Vessel Produced of HSLA Steel
(Journal Iron Steel Research Editorial Board, Beijing, 2011)
Welded joint is a critical region of a welded structure. The operational safety of welded pressure equipment mostly depends on the behaviour of loaded weldments. Safety of welded structure is dependent on the properties ...
The influence of silica fume and curing regime on some properties of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2014)
The investigation of posibilities of concrete structure modification by silica fume to improve concrete properties was presented in this report. Percentage of silica fume in regard to cement varied between 0% and 20%. ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Durability of concrete with different types of cement
(Procema SA, 2016)
Adequate measures must be taken during the determination of the concrete composition for ensuring the durability of concrete exposed to an aggressive environment. The influence of the cement type on the freeze/thaw resistance ...
Investigation of high temperature behavior and sintering mechanism of fly ash based concretes
(Procema SA, 2014)
Four types of refractory concretes were studied at various temperatures ranging from ambient to adopted maximal 1400 degrees C. The concretes had same matrix composition: K concretes were based on corundum aggregate; B ...
High-temperature concrete binders based on fly ash
(Revista Romana de Materiale/ Romanian Journal of Materials, 2013)
High-temperature concrete binders in which fly ash, as environmentally harmful secondary raw material, is combined with masonry and refractory cement is a new option for reapplication of this coal combustion by-product. ...
Process parameters influence on microstructural properties of hypereutectic al-18wt% Si alloys obtained by rheocasting process
(Editura Stiintifica Fmr, Bucharest, 2012)
Hypereutectic Al-18wt%Si alloy was obtained by conventional and rheocasting procedure at cooling rate 0.16 +/- 0.05 degrees Cs-1. Samples of rheocasted alloy were obtained at two stirring speeds 1000 and 1500 rpm. Tests ...
Water retention parameters and sediment dispersivity of the Zemun loess plateau (Belgrade, Serbia)
(Publ House Bulgarian Acad Sci, Sofia, 2019)
The paper presents the results of recent investigations of the Zemun Loess Plateau, which focused on unsaturated and dispersive loess soil. Soil water retention curves, SWRCs, were determined experimentally, using a pressure ...
Effect of absorption on active pressure in floury soil
(Pleiades Publishing Inc, Moscow, 2015)
Retaining walls are often built in unsaturated soil at shallow depth above groundwater level. It is critical to define active pressure in unsaturated soil for designing retaining walls, based on the expanded theory of ...
Ex post analysis of road projects: resilience to crisis
(Editorial Board EJTIR, 2018)
This investigation aimed to reveal a mechanism of how different road projects' settings respond to macro-economic crisis. Qualitative and quantitative analyses were performed over a sample of 31 European road projects, in ...
