Polyvinyl Alcohol (PVA, PVOH) is being used in the development of high-strength building materials that are more durable and environmentally friendly than traditional materials. Researchers at the University of California, San Diego, have created a new type of concrete that is made from PVA and is twice as strong as traditional concrete. The new concrete is also less prone to cracking and is more flexible, making it ideal for use in earthquake-prone regions. The use of PVA in building materials could have a significant impact on reducing the carbon footprint of the construction industry.
