Investigation of thermally induced processes in corundum refractory concretes with addition of fly ash
(Springer, Dordrecht, 2015)
The effects that the fly ash addition has on the behavior of thermally resistant corundum concrete were discussed. Experimental program implied production of two refractory composites: "referent" concrete from 20 % of ...
A Kinetic Study of Limestone Dry Micronization in an Ultra-Centrifugal Mill with Peripheral Comminuting Path
(Goller Verlag Gmbh, Baden Baden, 2017)
Because of its physico-mechanical and physico-chemical characteristics, fine-ground (i.e. micronized) limestone is widely applied in the production of new materials. Limestone can be used as a filler, coating and/or powder ...
Evaluation of Lignite Fly Ash for Utilization as Component in Construction Materials
(Taylor & Francis Inc, Philadelphia, 2013)
Utilization potential of fly ash, as the main residue in the lignite coal combustion in Serbian power plants, was investigated in present study. High production of fly ash represents extreme hazard for environment. Question ...
Geometry, mechanical properties and mounting of perforated plates for ballistic application
(Elsevier Sci Ltd, Oxford, 2010)
In this paper, the ballistic resistance of perforated plates made of different types of steel, mounting and geometry was investigated. Different types of steel in various heat treatment conditions were tested. Target ...
Wire fence as applique armour
(Elsevier Sci Ltd, Oxford, 2010)
In this paper, the behaviour of wire fence was investigated for potential as applique armour. The wire fence used was made from commercial high-strength patented wire and the supporting frames were made of mild steel ...
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 ...
Dehydration investigations of a refractory concrete using DTA method
(Springer, Dordrecht, 2012)
The base mix refractory concrete is corundum-based, containing corundum as refractory aggregate and CAC as hydraulic binder, with a spinel as an additive. The authors investigated the dehydration reactions which occur from ...
Application of Results of Nondestructive Testing Methods in the Investigation of Microstructure of Refractory Concretes
(ASCE - American Society of Civil Engineers, 2010)
The aim of this investigation is to establish the correlation between concrete porosity, compressive mechanical strength, and microstructure using the results of nondestructive testing methods, i.e., ultrasonic pulse ...
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 ...
Comparative analysis of process parameters of talc mechanical activation in centrifugal and attrition mill
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2014)
The efficiency of talc mechanical activation by means of two different mechano-activators centrifugal and attrition mill is investigated in this study and the comparative analysis of the characteristics of obtained talc ...
