Determination of recycled aggregate concrete degradation by resonance frequency analysis
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The evaluation of the dynamic modulus of elasticity of twelve different concrete mix proportions as a function of the density and degradations due to freeze/thaw cycles is presented in this paper. Pore system and saturation ...
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 ...
Influence of increased temperature on clay fast drying process
(Revista Romana de Materiale/ Romanian Journal of Materials, 2009)
In this paper are presented testing results during process of fast drying at conditions of increased temperature. Three different masonry raw materials were examined using recircular laboratory dryer with air recirculation. ...
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 ...
Influence of mineralizers on mullite synthesis
(American Ceramic Society, 2006)
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 ...
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, ...
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 ...
