Can graphite powder be used for concrete?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9~2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals.
Generally, stone toner is not used for concrete.There is no standard used or not used in this respect.Individuals believe that in order to form black concrete, it is feasible to add a small amount of graphite powder to concrete, but it should be proved to be in conformity with concrete standards and shall be reported to the business management department for approval.
