Blast Furnace Slag Disposal System

Blast Furnace Slag Cement - Manufacture, Properties and Uses.

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.

Estimated Longevity of Reducing Environments in Grouted .

long reducing conditions could persist in near-surface slag-bearing grouted systems for radioactive waste disposal. The oxidant of most concern is oxygen (O2)—in the gas phase or dissolved in infiltrating water—which could react with the blast furnace slag and decrease the grout reductive capacity.
