The American Chemical Society has good news for the construction industry when it comes to finding the proper materials to rebuild America’s crumbling bridges and roadways. On March 29 at the National Meeting & Exposition of the American Chemical Society, an exciting way to save billions of taxpayer dollars was presented. The new coating material for concrete is known as flyash, and it is made from left over burning coal. This material could extend the life of structures by decades, and is hundreds of times more durable than existing coatings and costs half as much.
More than 130 million tons of “flyash” are created every year, byproducts of the more than 450 coal-burning electric power plants in operation throughout the United States. This ash, which before the anti -pollution laws flew up into smokestacks and into the air, power plant officials collect with loving care.
Flyash is not without its problems, as almost 70 % of it winds up in landfills every year. Researchers at the American Chemical Society are trying to turn that aspect around because they are certain that this waste could be transformed into a valuable resource. Flyash acts as a shield on concrete, which keeps it from crumbling as it ages.
Significant laboratory testing reveals that the coating maintains strength and durability when exposed to heat, cold, rain, and other simulated climactic conditions, which are harsher than any that would occur in the real world.
This new material represents a giant step in sustainable living and the recycling of materials. What was once waste is now a source of cheap and powerful energy.
Saving this planet must be everyone’s business and hats off to the American Chemical Society!
