Synthesis, characterization and application of the filler based on corundum for obtaining the ceramic coats in foundry
(Editura Stiintifica Fmr, Bucharest, 2012)
In this work, a possibility to develop new ceramic coats based corundum for casting applications has been examined. Optimization of coating composition with controlled rheological properties was attained by applying different ...
Some properties of concrete based on recycled bricks
(Revista Romana de Materiale/ Romanian Journal of Materials, 2010)
By using crushed brick as aggregate, the structure of concrete can be effectively modeled and materials with very different physical-mechanical characteristics can be obtained. Determination of the influence of polymer ...
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 ...
The possibility of substitution of wear resistant low chromium white iron resistant with basalt melt
(Editura Stiintifica Fmr, Bucharest, 2012)
In this study the testing results of the possibility of substituting mill lining plates for ore milling made of low chromium white iron that is resistant to wear with plates made of basalt melt are presented. Plates made ...
Future Armoured Troop Carrying Vehicles
(Defence Scientific Information Documentation Centre, Delhi, 2010)
Present-day reliance on wheeled and tracked armour personnel carriers (APCs) and infantry fighting vehicles (IFVs), may be changed in the future. Shaped charge grenades and impovised explosive devices (IEDs) represent a ...
Characterisation of high-carbon steel surface welded layer
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
In this paper microstructural and mechanical properties of high-carbon steel surface welded layer, obtained with self-shielded flux cored wire, are presented in the case of a standard rails and crossings. The testing results ...
Mechanical properties of ultra high performance self compacting concrete with different mineral admixtures
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
Preparation and microstructure of ultra high performance concrete (UHPC) have been intensively analyzed In the last few years. The mechanical properties (compressive strength and flexural strength) were investigated under ...
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 ...
Determination of the effective diffusion coefficient
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The equation for drying kinetics is obtained, base on the analytical solution of the differential equation with a boundary condition in the form of the flux. This equation was initially developed by G. Efremov. In this ...
Influence of drying constant adn diffusivity of clay drying behavior
(Industrial Ceramics, 2007)
The influence of the correlation between the drying constant and the diffusion coefficient of the liquid on the behavior of two raw materials for brick manufacturing during their drying process was examined. The test was ...
