dc.description.abstract | 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, as well as reusing waste materials instead of disposing them in landfills, contributes significantly to the protection of the environment. Also, the price of waste
materials is usually much lower than the price of raw materials used for production of PC.
Coal combustion in thermal power plants produces huge amounts of fly ash (FA). It is estimated
that 500-750 million tonnes of FA are generated worldwide annually, with a global utilization rate
of only 25 %. Due to pozzolanic properties of this aluminosilicate waste material, FA has been
used as PC component for decades. However, the broad use of binders made of high volume of
FA (>50%) is limited by their relatively long setting time and low early strength.
The other waste material of interest in this work was fluid catalytic cracking catalyst residue
(FC3R), a by-product from petrol refineries, which primarily consists of zeolite and amorphous
aluminosilicates and also shows pozzolanic activity. Due to relatively small quantities of FC3R
produced (~160000 tonnes per year globally), landfilling is usually considered as the most
economical option for its disposal.
The aim of this work was to investigate the performance properties of ternary binder containing
high volume of the two different waste materials, FA and FC3R. The binder consisted of FA,
FC3R, and PC (commercial CEM I) mixed in a 49:21:30 mass ratio. Both waste materials were
mechanically activated prior to the binder synthesis. Characterization of raw and mechanically
activated waste materials via determination of particle size distribution, morphology and mineral
composition, was conducted. Analyses of the ternary binder properties showed that using FC3R
as the binder component resulted in acceleration of cement hydration and pozzolanic reaction. The
ternary binder had shorter setting time and higher early strength than the control binder
synthesized with 70 mass% of FA and 30 mass% of PC. | sr |
