Self-Cleaning Concrete - National Precast Concrete Association

Aug 24, 2020 · Self-cleaning concrete works by adding a catalyst, usually titanium dioxide, to the fresh concrete mix. Titanium dioxide activates in the hardened concrete when exposed to the sun. The activation changes titanium dioxide’s electric charge, causing a repelling effect between the concrete and the dirt and pollutants on the concrete surface.

Applications of using nano material in concrete: A review

Apart from that, inclusion of PCE at required dosage will produce Self Compacting Concrete (SCC). SCC increases the workability of concrete and produces a flow concrete which gives great impact during the placing of concrete at low and high intensity area. ... This is the most widespread form of titanium dioxide-bearing ore around the world ...
