Indian steel industry has to look forward to utilize the excess availability of iron ore fi nes.

The research on whether can iron ore tailing improve the compressive strength of alkali-activated slag ing concrete is conducted. The experiment shows that too little or too much powder from iron ore tailing will reduce the compression strength of alkali activated slag concrete, when powder from iron ore tailing achieving optimal amount, the compression...

Lamani S R et al. investigated the utility of iron ore waste (IOW) in preparing non-fired bricks by using cement and fly ash. Bricks were prepared with different proportions of cement, fly ash, and IOW. The manufactured bricks were cured for 7, 14, 21, and 28d. Compressive strength and water absorption of bricks were evaluated.

Compressive strength or hardness measures how well a material resists being squeezed together. One way to determine this is to use the Mohs scale, with values from 0 to 10, with 10 being the hardest. Yield strength refers to how well a rod or beam of a particular metal resists bending and permanent deformation. This is an important measure for ...

1.1 This test method describes a method for determining the crushing strength of fired iron ore pellets and direct-reduced iron. Cylindrical agglomerates and briquettes are not covered by this test method. 1.2 The values as stated in SI units are to be regarded as the standards. The values in parentheses are given for information only.

Green pellet strength and plasticity are important parameters for the productivity of an iron ore pelletizing plant. Green pellet strength is described by two test values, that is by drop number and compression strength. The drop number describes the green pellet strength during a fast impact such as the impact that occurs during unloading

The white cast iron is heat-treated (Annealing) at about 950 Degree Celsius for 24 or 48 hrs and then allow to cool for 24 hrs or 48 hrs. This changes the carbon in the iron carbide of the cast iron into graphite and ferrite plus carbon. Nodular graphite is present in the malleable cast iron. Properties. It has excellent strength and toughness.
