Do you remember the story of the\nthree little pigs? In that fairy tale, the pigs used straw, sticks and bricks\nwhen building their houses. And when that big, bad wolf came along, which house\nstood up to all his huffing and puffing? The one made of bricks, of course.\nThat’s because the bricks were held together with a mixture of cement, sand and\nwater called mortar. So cement must be pretty tough stuff, right? Well, not on\nits own. But mixed with other things, cement is REALLY useful. <\/p>\n\n\n\n

\nA Concrete Example
\n<\/strong>If you mix cement\nwith gravel, sand, certain chemicals and water, you get concrete. And concrete\nis used EVERYWHERE.  It’s the world’s most commonly used human-made\nmaterial. Buildings, bridges, sidewalks, patios, foundations — they can all be\nmade from concrete.  <\/p>\n\n\n\n

Now that we know how important\nconcrete is, and that you need cement to MAKE it, we need to learn a bit more\nabout the creation of cement.<\/p>\n\n\n\n

A Carbon Dioxide Dilemma
\n<\/strong>Cement is made by combining\nmaterials like limestone and clay and then heating them up to SUPER hot\ntemperatures in a cement kiln (we’re talking over 1400 degrees Celsius!).\nDuring this process, carbon dioxide (also known as CO2<\/sub>) is released.\nAnd that’s a problem.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Because as you know, brilliant\nEarth Ranger, extra carbon dioxide in the atmosphere traps thermal energy,\nwhich causes the greenhouse effect and leads to global warming. That’s why we\nneed to control how much CO2 <\/sub>is produced and released by\nmanufacturing. Thankfully, some clever people at Ash Grove Cement have figured\nout they can capture the carbon dioxide before it enters our atmosphere.<\/p>\n\n\n\n

Capturing Carbon Dioxide
<\/strong>Carbon dioxide can be captured when it’s released, but before it exits the chimney of the cement manufacturing plant. When it’s captured, there are two things that can be done with it: the carbon dioxide can be stored deep underground, or it can be used in the production of other products like plastics, concrete, biofuel, and even carbon nanotubes. The second option is obviously the best one — if we can reuse CO2 <\/sub>instead of just storing it somewhere, that’s best for everyone…and for the Earth!<\/p>\n\n\n\n
