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 ... -
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 ... -
Effects of sucrose and sorbitol on cement hydration applications to cement stabilization of metal waste
(2007)Cement-based stabilization/solidification (S/S) is a widely used technique to treat industrial wastes containing toxic metal ions before land disposal. To prevent the fast setting of the treated waste during its transportation ... -
Evaluation of GaN and InGaN semiconductors as potentiometric anion selective electrodes
(2006)Ion selective electrodes (ISEs) are chemical sensors primarily used for in situ analysis and monitoring of air, water, and land. Despite their easy fabrication, low cost, and simple usage, ISEs still suffer from the ...
