TL;DR: In this article, a new method, based on the use of silica fume, for heavy metal stabilization was discussed and compared with other technologies, involving the employ of amorphous silica as stabilizing agent for municipal solid waste incinerator fly ash treatment.

TL;DR: In this article, the authors examined the resistance of seven different concrete mixtures against a 0.5% sulfuric acid solution and found that the mixture with addition of silica fume was most vulnerable to corrosion.
Abstract: The resistance of seven different concrete mixtures against a 0.5% sulfuric acid solution was examined. The difference between high sulfate resistant Portland cement and blast furnace cement, as well as the influence of polymer modifications of the concrete and the addition of silica fume were issues of the investigation. All concrete mixtures were submitted to an alternating immersion and drying during 18 weeks in a 0.5% sulfuric acid solution using a testing apparatus for accelerated degradation tests. The corrosion of the concrete was quantified by measuring the change in dimensions of the test specimens with laser sensors. The mixture with addition of silica fume was most vulnerable to corrosion. Depending on the polymer type used, polymer modification of the concrete resulted in an increase and a decrease in the resistance of the concrete respectively. The concrete made with blast furnace cement had the highest resistance of all tested concrete types.
