Some Issues of Shrinkage-Reducing Admixtures Application in Alkali-Activated Slag Systems
(MDPI, 2016-06-10)
Significant drying shrinkage is one of the main limitations for the wider utilization of alkali-activated slag (AAS). Few previous works revealed that it is possible to reduce AAS drying shrinkage by the use of shrinkage-reducing ...
Efect of Chemical Aggressive Media on the Flexural Properties of Cured-In-Place Pipes Supported by Microstructure Observation and Acoustic Emission
(MDPI, 2020-07-08)
The cured-in-place pipe (CIPP) method is currently the most frequently used approach for
the renovation of piping without digging; this technology is suitable for pipes made from all types of
material. The authors of this ...
Impact of Aggressive Media on the Properties of Polymeric Coatings with Solidification Products as Fillers
(MDPI, 2019-11-26)
Dealing with waste materials, particularly hazardous waste, is a serious problem. Disposal
areas keep growing, and the costs incurred are high. Disposing of such waste reduces negative
environmental impacts and offers ...
Repairing composite using hazardous waste containing heavy metals
(IOP Publishing, 2018-07-16)
This research deals with the possibility of using hazardous waste in epoxy resinbased polymeric substances. More specifically, it is the use of neutralising galvanic sludge (NGS), which produces as a by-product in the ...
Effect of wood chips properties on mineralogical composition and microstructure of silicate matrix based composites
(IOP Publishing, 2018-07-16)
The research presented in this article was focused on proving the effect of wood chips parameters on the hardening process of silicate matrix in cement-bonded particleboard. Namely content of humidity in the chips (in range ...
Electrical and Self-Sensing Properties of Alkali-Activated Slag Composite with Graphite Filler
(MDPI, 2019-05-16)
The electrical properties of concrete are gaining their importance for the application in building construction. In this study, graphite powder was added to alkali-activated slag mortar as an electrically conductive filler ...
Immobilization of Heavy Metals in Natural Zeolite-blended Cement Pastes
(Elsevier, 2016-09-26)
This paper deals with the investigation of efficiency of natural zeolite-blended cement pastes for the immobilization of heavy metals. Natural zeolite was used to partially replace ordinary Portland cement (OPC) at rates ...
Monotonic and cyclic properties of TiAl alloys Monotic and cyclic properties of TiAl alloys doped with Nb, Mo and C
(Elsevier, 2014-06-25)
Six grades of TiAl alloys doped with 7 at.% Nb and variable content of C and/or Mo were studied. The as-received
microstructure and phase composition of the alloys was characterized using neutron diffraction experiments ...
Blended alkali-activated fly ash / brick powder materials
(Elsevier, 2016-08-08)
Aluminosilicate materials can be transformed into very compact binding material by the process called alkaline activation. The paper presents results of alkaline activation of fly ash and waste fine-grained brick body. ...
Nitrogen Interstitial Alloying of CoCrFeMnNi High Entropy Alloy through Reactive Powder Milling
(MDPI, 2019-04-04)
The present work is focused on the synthesis of CoCrFeMnNi high entropy alloy (HEA) interstitially alloyed with nitrogen via powder metallurgy routes. Using a simple method, nitrogen was introduced to the HEA from the ...
