Concrete is the most widely used construction material in the world, second only to water. Over time, as a result of the build-up of atmospheric compounds in the surrounding environment, concrete will become discolored, stained, dirty, and dingy. This course examines photocatalytic technology which accelerates self-cleaning and fights air pollution while maintaining the mechanical and physical properties of traditional concrete.

Upon completion of this course, the Learner should be able to:

• Review the history of photocatalytic technology and evaluate how applying it in concrete can improve the sustainability and performance of a building.
• Explain how photocatalytic cement speeds up the natural, self-cleaning oxidation process of concrete, thus preventing the accumulation of atmospheric compounds on its surface, reducing discoloration and preserving aesthetics.
• Convey how photocatalytic technology abates air pollution, thereby reducing smog and decreasing atmospheric elements which damage the air we breathe, and in doing so, improving human health and that of the environment.
• Recognize how photocatalytic cement products contribute to a sustainable built environment through reduction of the heat island effect, improving energy performance and durability.
• Determine the factors that influence performance, review independent laboratory and field verification trials, and assess specific case studies and the cost value factors associated with the technology.
