MaterialsDomestic material consumption (DMC) refers to the amount of materials (in terms of weight) used in an economy, materials extracted or harvested in the country, plus materials and products imported, minus material and products exported. The data refer to metals, nonmetallic minerals (construction minerals, industrial minerals), biomass (wood, food) and fossil energy carriers.
Global Consumption Database | The World BankAbout the database. The Global Consumption Database is a onestop source of data on consumption patterns in developing countries. It is designed to serve a wide range of users—from researchers seeking data for analytical studies to businesses seeking a better understanding of the markets into which they are expanding or those they are already serving.
Cement: Materials and manufacturing processCement: Materials and manufacturing process. • Chemically, cement is a mixture of calcium silies and small amounts of calcium aluminates that react with water and cause the cement to set. • Calcium derives from limestone and clay, mudstone or shale as the source of the silica and alumina. • The mix is completed with the addition of 5% ...
