Optimization of mechanical activation of fly ash
(Institute for multidisciplinary research, 2019)
More than 5.5 million tonnes of fly ash (FA), a by-product originating from coal combustion in thermal power plants (TPP), is produced in Serbia annually. Only small part of the FA is reused, mostly by cement industry, ...
Resistance to external sulfate attack - Comparison of two alkali-activated binders
(E D P Sciences, Cedex A, 2018)
Durability of binders, mortars and concretes in aggressive environments is of crucial importance for their commercial application. In this paper the resistance to external sulfate attack of two different alkali-activated ...
Methods to improve fly ash reactivity and increase its reuse potential in construction materials industry
(9th International Advances in Applied Physics & Materials Science Congress & Exhibition, APMAS 2019, Oludeniz/Mugla, Turkey, 2019)
Fly ash, a by-product from coal combustion in thermal power plants, is one of the most abundant anthropogenic materials. It is estimated that between 500 and 750 million tonnes of this material is generated worldwide ...
Microscopy and microanalysis of alkali activated fly ash binder
(F.A. Finger-Institut fur Baustoffkunde, Bauhaus-Universitaet Weimar, Germany, 2012)
Large quantities of fly ash (FA) are produced worldwide by burning of pulverized coal in the thermal power plants. It is a dustlike material which usually contains significant amount of amorphous phase due to rapid cooling ...
Possibility to use spent fluid catalytic cracking catalyst as component of Portland cement binders
(Faculty of Technology, University of Novi Sad, 2019)
Fluid cracking catalyst residue (spent FCC) is a by-product from petrol refineries. It primarily consists of zeolite (in used sample - faujasite) and amorphous aluminosilicates. In this study, possibility to use spent FCC ...
Comparison of two alkali-activated systems: mechanically activated fly ash and fly ash-blast furnace slag blends
(Elsevier Science Bv, Amsterdam, 2015)
Poor reactivity of fly ash (FA) in alkali activation process can be improved either by mechanical activation of fly ash or by blending fly ash with more reactive material, such as blast furnace slag (BFS). Both options ...
THE RELATIONSHIP BETWEEN FLY ASH-BASED GEOPOLYMER STRENGTH AND MAJOR STRUCTURAL ELEMENTS
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Geopolymers are relatively new type of inorganic binder materials, which can partly substitute Portland cement. Application of geopolymer binders is very favorable from ecological point of view for two reasons: because of ...
Characterisation of fly ash-based geopolymers activated with sodium silicate
(University of Belgrade, Technical Faculty in Bor and Mining and Metallurgy Institute Bor, Serbia, 2014)
The present work examines the effects of sodium silicate activating solution on the properties of fly ash-based geopolymers. Various geopolymers were synthesized utilizing fly ash, sodium silicate solution and NaOH. Moduli ...
Durability of alkali activated materials
(Institute for Multidisciplinary Research, University of Belgrade, 2015)
In the last decade, great scientific attention has been devoted to alkali activated materials, including geopolymers and other related materials. These materials are seen as promising alternative binders, with a possibility ...
