Concrete is the most popular construction material in out planet. Today, about 5-8% CO2 by human activities has source from Portland cement manufacturing, which is an indispensable binding material of normal concrete. However, reseachers have just a result to new kind of concrete that can replace for normal concrete using Portland cement: Polyme concrete.

Research project has the result of green concrete, which is new polyme concrete technology. The above image is a 5000lb (453.6 grams = 1lbs) cement block using "flying ash".

Portland cement is very popular now, with total quantity estimation about 2.6 billion tons/year and annual increase of 5% each year. To inhibit polluting speed on the world, Dr. Erez Alloche, teaching assistant and vice president of Trenchless Technology Center about design and construction of public projects at Lousiana Technology University (U.S.) is implementing a creative research project about polyme concrete (geopolymer), using redundant products from electricity mills that operate with coals.

This kind of general polyme concrete uses binding elements from "flying ash" (smooth waste from burning coal dust of thermoelectricity factory, with main ingredient is oxide of silic, iron, canxi, magie, aluminium and brimstone. In addition, there is an amount of unfire coals, not over 6% quantity of flying ash) - abundant by-product that can replace Portland cement.

Polyme concrete has many advantages to compare with normal concrete. Firstly, it can limit the amount of CO2 and create an infrastructure with long time using. By salvaging "fly ash", it can free a wide area of ground to use as an inventory for pit coal and protecting water source from pollutants.

Comparing to normal Portland cement (OPC), polyme concrete has more useful characteristics (erosion resistance, heat resistance to 2400 Fahrenheit degree, press, elastic degree...)

According to researchers, the biggest advantage of polyme concrete is the ability to reduce amount of greenhouse gas, about 90% to compare with OPC. It is a technology for the future to reduce energy demand of human beings.
