artificial coarse aggregates used in railways

Experimental study of cold - Bonded artificial lightweight . Aggregates are used in concrete for a very specific purpose. The use of coarse and fine aggregates in concrete provides significant economic benefits to the final cost of concrete since they are the least expensive materials used in concrete and generally make up about 60 to 75 percent of the volume of concrete mixture.
