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 ... -
Durability and mechanical properties of Portland cement concrete that utilizes crumb rubber as an alternative fine aggregat
(2018)This research project investigated in an intensive experimental program the influence of using crumb rubber in the mechanical properties and durability of Portland cement concrete mixtures. Crumb rubber is produced from ... -
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 ...
