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 ...
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 ...
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 ...
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 ...
Influence of Processing Techniques on Microstructure and Mechanical Properties of a Biodegradable Mg-3Zn-2Ca Alloy
(MDPI, 2016-10-28)
New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of ...
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 ...
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 ...
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 ...
