Study on Processed Granulated Blast Furnace Slag as a Replacement for Fine Aggregates for the Greener Global Construction

Laboratory evaluation of a complex treatment technology for reducing water absorption of the pavement subbase aggregate from the blast-furnace slag

“…A large number of scientific studies have been devoted to the problems of recycling industrial wastes of metallurgical production, including BFS [1][2][3][4][5][6]. A special place among the areas of research in the field of recycling blast-furnace and steel-smelting slags is occupied by the possibility of use these materials in construction and civil engineering [7][8][9][10][11][12][13][14][15][16][17][18][19][20], including production of cement [7][8][9], mortars, slag-alkaline binders [10,11], concrete [12][13][14], fine and coarse aggregates [15][16][17], mineral wool [18], ceramic paving stones [19], geopolymers [20]. The vast majority of studies is aimed at testing cements and concretes containing granulated blast-furnace slag (GBFS) and other industrial wastes for strength, studying the effect of GBFS percentage in concrete composition on its performance properties, the relationship between the mechanical properties of slag concrete and its microstructure, mathematical modeling of the strength of concrete containing GBFS, the use of GBFS instead of sand as a concrete aggregate, determination of the binding properties of slag cement, obtaining alkali-activated slag cement.…”
