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 ...
Effect of particle size of waste brick powder on the properties of alkaline activated materials
(IOP Publishing, 2018-07-12)
The properties of alkaline activated brick dust mixed with water glass with a silicate
modulus (Ms) of 1.0 were studied in fresh mixtures as well as hardened products in connection
with the particle size of the dust. The ...
Synthesis of high density sub-10 µm (Ba0.85Ca0.15) (Zr0.1Ti0.9)O3-xCeO2 lead-free ceramics using a twostep sintering technique
(TAYLOR & FRANCIS LTD, 2019-10-29)
(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3-xCeO2, (BCZTCe) lead-free piezoelectric ceramics were processed conventionally using a two-step sintering technique. The results suggest that two-step sintering is an effective technique to ...
Characterization of geopolymers prepared using powdered brick
(Elsevier, 2019-11-01)
Geopolymerization of waste products can contribute to the solution of current environ-mental issues related to depletion of natural resources. In this paper, several geopolymer mixes are prepared using waste brick in ...
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 ...
Influence of Micro-Structure on the Fatigue Crack Propagation in Bridge Steel
(MDPI, 2018-06-19)
The use of high strength steels (HSS) allows designing lighter, slenderer and simpler
structures with high structural performance. In general, the use of HSS leads to weight reduction of
the whole structure, which compensates ...
Thermal behaviour of metakaolin/fly ash geopolymers with chamotte aggregate
(MDPI, 2016-06-30)
Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200–1200 °C on the mechanical properties and ...
Effect of alkaline activator quantity and temperature of curing on the properties of alkali-activated brick dust
(IOP Publishing, 2018-07-16)
The properties of alkaline activated brick dust mixed with different amounts of
water glass with a silicate modulus (M) of 1.0 were studied in connection with the temperature
of curing. The influence of the amount of ...
Microstructural study of AZ91C magnesium alloy castings produced by investment casting in as-cast state and after heat treatment
(Tanger Ltd., 2019-05-24)
In this article, the microstructure of AZ91C magnesium alloy castings produced by investment casting was investigated. Castings were studied in as-cast state and after T4 and T6 heat treatment. The identification of all ...
