Cement
World production is about four billion tonnes per year, of which about half is made in China. If the cement industry were a country, it would be the third largest carbon dioxide emitter in the world with up to 2.8 billion tonnes, surpassed only by China and the United States.

One Wind Turbine Takes 900 Tons of Steel , 2500 Tons Of Concrete , 45
Building one wind turbine requires 900 tons of steel, 2,500 tons of concrete and 45 tons of plastic. Democrats dream of powering society entirely with wind and solar farms combined with massive batteries. Realizing this dream would require the biggest expansion in mining the world has seen and would produce huge quantities of waste.

Is Concrete Sustainable? Here’s Why We Need To Talk About Green
In the US, portland cement production accounts for about 0.33% of the annual energy consumed, which is equivalent to the amount of energy in around 13 million tons of coal. It is also true that cement has a lower embodied energy (the sum of all the energy required to produce something) than materials such as steel or aluminium, meaning that it’s not a simple solution of changing to another

How aluminium is produced
First alumina is stacked into piles weighing up to 30,000 tonnes. In the end a kind of layered pie 10-12 metres high is built in this manner. The pile is then cut and loaded into railroad cars, 60-75 tonnes per car (depending on the type of car) for dispatch to smelters. There is another far less common method for making alumina.

Cement & Concrete Basics FAQs
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.
