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 ...
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, ...
Performance of ternary cement binders containing high volume of fly ash and fluid catalytic cracking catalyst residue
(Materials Research Society of Serbia, 2022)
The use of binders based on waste materials in construction industry has both ecological and
economic advantages over the use of commercial Portland cements (PC). Preserving the natural
resources needed for PC production, ...
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 ...
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 ...
Chemical activation of high volume fly ash binders by selected sodium salts
(Institut za multidisciplinarna istraživanja, 2023)
Fly ash (FA), a by-product of coal combustion in thermal power plants, has been widely used in construction industry as partial replacement for Portland cement (PC). Due to environmental protection requirements, it became ...
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 ...
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 ...
ENHANCING THE REACTIVITY OF THE INDUSTRIAL FLY ASH IN THE PROCESS OF ALKALI ACTIVATION
(Institut za multidisciplinarna istraņivanja Kneza Vińeslava 1, 11000 Belgrade, Serbia, 2023)
Over the past few decades a new group of binding materials, geopolymers, have
emerged as an alternative to traditional binding materials such as Portland cement.
Geopolymers are obtained by the process of alkali activation ...
IMPROVED PROPERTIES OF ALTERNATIVE BINDERS AND THEIR POTENTIAL APPLICATION FOR SOIL STABILIZATION
(University „Union-Nikola Tesla”, Belgrade, Serbia, 2023)
This paper investigates the influence of mechanical activation of different
types of fly ash on the properties of alternative binders – geopolymers based on
alkali activated fly ash. Fly ash was firstly mechanically and ...
