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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
