Removal of Hexavalent Chromium in Portland Cement Using Ground Granulated Blast-Furnace Slag Powder
Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) ...
متن کاملLimestone and Silica Powder Replacements for Cement: Early-Age Performance.
Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supplies of many alternatives to OPC (such as fly ash or slag) may be limited, those of limestone and silica powders produced by crushing rocks seem virtually endless. The present study examines the chemical and physical influ...
متن کاملOptimum conditions for adsorptive storage.
The storage of gases in porous adsorbents, such as activated carbon and carbon nanotubes, is examined here thermodynamically from a systems viewpoint, considering the entire adsorption-desorption cycle. The results provide concrete objective criteria to guide the search for the "Holy Grail" adsorbent, for which the adsorptive delivery is maximized. It is shown that, for ambient temperature stor...
متن کاملPolymer-Cement Composites Containing Waste Perlite Powder
Polymer-cement composites (PCCs) are materials in which the polymer and mineral binder create an interpenetrating network and co-operate, significantly improving the performance of the material. On the other hand, the need for the utilization of waste materials is a demand of sustainable construction. Various mineral powders, such as fly ash or blast-furnace slag, are successfully used for the ...
متن کاملOptimum Test Sequence Generation from Estelle Specifications
The recent research results from the Protocol Engineering Lab of the University of Delaware in minimum-length test generation based on Estelle speci cations are summarized. The methods use models restricting the number of self-loops to be consecutively traversed for each state, and utilizing semicontrollable interfaces of the IUT to increase the number of testable transitions. The initial resul...
