Admixtures for use in geopolymers
(2012-11-10)This study examined two novel approaches for the geopolymerisation of fly ash produced at thermoelectric power stations by combustion of coal. The first approach involved the use of cullet, a post-consumer glass waste, to ... -
Analysis and simulation of K and Cl in electrostatic precipitator ash and black liquor of an operating kraft recovery boiler
(2023)Non-process elements such as potassium (K) and chlorine (Cl) are commonly found in the recovery cycle of kraft mills and are capable of forming highly soluble compounds. These elements, in high concentrations, can lead ... -
Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ... -
Comparison of methods to determine the carbonation depth in fly ash blended cement mortars
(2014-01-22)Carbonation negatively affects the durability of steel-reinforced concrete structures by causing a decrease in pore solution pH, thus facilitating corrosion which eventually leads to cracking and spalling. Different ... -
Effect of carbonation on leachability and compressive strength of cement-solidified and geopolymer-solidified synthetic metal wastes
(2012-11-10)Stabilization/solidification (s/s) is a well-established technique for treating a variety of metal-containing hazardous waste streams prior to land disposal. Solidification refers to the improvement of the physical ... -
Low CO2 methanol by methane pyrolysis in catalytic liquid metal bubble reactor
(2022)Methanol production based on methane pyrolysis presents an opportunity for CO2 utilization and lower CO2 emissions than traditional methanol production processes that are based on methane reforming. This research employs ...
