The properties of compositions based on mixtures of Portland cement and Secar 38 R aluminous cement with the addition of hemihydrate of calcium sulfate are examined. The effect of α- and β-hemihydrate of calcium sulfate addition on the time of curing, kinetics...
A method is proposed to use existing dust filtration with a sorbent, insensitive to temperature and harmless with respect to concrete, in order to capture mercury and use the kiln dust where the sorbent is contained. The sorbent binds mercury, to be subsequently leached...
