If you read the linked article, you will see that the cost of the TX Active concrete is quoted as being one third more expensive than traditional concrete. Titanium dioxide (the active "ingredient") is very commonly used already in various industries, so I can't imagine the cost of producing the compound is too shocking. Using TiO2 for this purpose isn't a new concept, either, just a new application of it. The materials division of Mistubishi rolled out a similar product in the form of pavers a while back.
