Paper Details

Concrete is the most abundant manmade material in the world. One of the main ingredients in a normalconcrete mixture is Portland cement. However, the production of cement is responsible for approximately 7% of theworld’s carbon dioxide emissions. In order to create a more sustainable world, engineers and scientists must developand put into use a greener building material. This paper will discuss the use of geo polymer concrete as well as considerits ethical issues. Additionally, this paper will explore the areas in which geo polymer concrete out performs ordinaryconcrete. Geo polymer concrete uses fly ash, a byproduct created from the burning of coal. Currently, the majority of flyash is dumped into landfills, causing environmental problems.The production of geo polymer concrete allows fly ash to be recycled and eliminated from landfills. Geo polymerconcrete is also more resistant to damage than standard concrete. For example, geo polymer concrete is stronger undertension and compression than its cement based counterpart. It is also more resistant to salts, acids, sea water corrosion,and fire. There are some disadvantages of geo polymer concrete that must be overcome before its incorporation into theconstruction industry, many of which will be discussed. Presently, it is difficult to create geo polymer concrete outside ofa laboratory setting as it is still being researched by engineers and scientists. However, if this material can be readilyand safely produced at low costs it will revolutionize the construction industry.
