Feasibility Study of Stone-Dust as an Alternative Material
The chemical composition of silica sand and stone-dust is reported in Table 3. It is observed that the silica sand contains 98.45% SiO 2, whereas stone-dust has only 66.23% SiO 2 and 18.79% of Al 2 O 3, and 5.34% of Fe 2 O 3. It is expected that the fusion point of stone dust will be lowered than silica sand.
