Concrete, widely used construction material suffers from cracks and low tensile strength that cut down the load capacity resulting in shortening of self-life. Biologically modified construction materi...
This study investigated the fate of polybrominated diphenyl ethers (PBDEs) in a thermal treatment system that was employed to recover the metals from the electric arc furnace (EAF) fly ash. After 145...
The entrained fine fly ash particles carried into the post-combustion region and collected by air pollution control devices were capable of such surface-mediated dibenzo-p-dioxin and dibenzofurans (P...
The effects of thermal treatment temperature and CaO addition on polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) content in the fly ashes from a medical waste incinerator with high chlo...
To the best of our knowledge, the formation mechanisms of PBDEs in the combustion system, fly ash, as well as their relation with temperature, have never been investigated. In this study, the formati...
Thermal treatment is often employed to recover the metals contained in electric arc furnace (EAF) fly ash, which is considered a major source of PCDD/Fs. After the present treatment, the mass and vol...
Pulverized fly ash (PFA) is produced about 500 billions tons every year in the world in a result of coals combustion. Most of the fly ash collected in power plants is disposed by deposition in landfil...
Properties of Roller Compacted Concretes with Fly Ash     Fly ash  RCC  Strength  Loss on ignition  Vibrating slump test       font style='font-size:12px;'> 2009/10/13
In this study, brief information on zero slump concrete, which is not in common use in Turkey, is given.Zero slump concrete, also known as roller compacted concrete (RCC), is produced at a very low wa...
Use of Fly Ash as a Potential Coagulant in the Physico-Chemical Treatment of Domestic Wastewater。
This paper presents part of the results of an ongoing laboratory study carried out to design a structural lightweight high strength concrete (SLWHSC) made with and without ternary mixtures of cement-f...
An experimental study was carried out to investigate the CBR behaviour of waste plastic strip reinforcedstone dust/fly ash overlying saturated clay. Three different sizes of waste plastic strips were ...
Castings were poured from PA9 aluminum alloy. Cores in the form of standard cylindrical specimens were made from the core mixture based on fly ash of the identified chemical and granular composition.
The addition of ultrafine powde(UFP)to concrete can improve the fluidity of concrete,showing a water-reducing effect. The aim of this article was to analyzi the water-reducing mechanism of UFP both ex...
Problems related in this study concern the possibility of improving the physico-chemical properties of fly ash used as a base granular material in moulding mixtures. The investigations were carried ou...
The author’s experimental researches presented in this paper were focused on the building materials obtained by using ultra-fine fly ash and silica fume (like heavy mortars or compacted lightweight co...
