 I'm Konstantin Sobolev and I'm an associate professor at the Department of Civil and Environmental Engineering at UWM. I am working on advanced concrete, which can be designed to be extremely durable. Unfortunately, very often we don't make it for extreme durability. And so what is why we are trying to develop new types of concrete, which is stronger, more durable, and at the same time, sustainable. Undergraded students involved in different research activities in my lab mixing and testing and deeply involved in current DOT project to make better concrete roads in this concern. Concrete is the largest man-made material. Here in Milwaukee, concrete is subjected to extreme environmental exposures. So developing better concrete for local applications is extremely important. We are working on photocatalytic concrete in our laboratory and one of the recent developments is to develop photocatalytic periose concrete. We developed a material which can also not only be pervious for water, but also clean air and clean water. And you can see that water can go through this concrete. In normal concrete, it's not really desirable to have water penetrating through concrete, but this concrete works as a filter so it can really filter rainwater through. So we developed superhydrophobic engineered cementitious composite which can repel water. This material is also ultra-strong, durable and also bendable. We use this concrete for repairing of our ramp to our parking garage. I'm Konstantin Sobolev and I'm a Milwaukee engineer. Thank you for watching.
