graphite in cement manufacturing process

Fabrication and characterization of graphite-cement ...

01/04/2017  Graphite-cement composites, with graphite up to 80% w/w, were prepared and characterized. The key feature of this novel material is its conductive and porous microstructure, due to a synergic effect between cementitious matrix and graphite particles. As graphite content increases, a characteristic percolation threshold exists.

How Concrete is Made - Cement

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
