  A review on alternatives to sand replacement and its effect on concrete ...

  2023324 · Concrete with walnut shells and Steel Slag (SS) as replacement of coarse aggregate and sand respectively reported that workability reduces when replacement is at 10% due to high water absorption property in steel as FA [6]. The increase in substitution of sand with Waste Foundry Sand (WFS) resulted in decreased slump.

  Fabrication of Baking-free Bricks from Iron Ore Tailings

  Results: The optimal components of the baking-free bricks are 65wt.% tailings, 5wt.% titanium gypsum, 17wt.% slag, 5wt.% acetylene sludge, 8wt.% waste brick powder. The optimal forming pressure is 10MPa. 28 d compressive strength and density of the baking-free bricks reach 19.8 MPa and 1622.92 kg.m -3, respectively.
