Unfortunately there's some bad news! about this cement  (which uses special compounds - TiO2 particles) also I've found recently:
>Lastly, there are some concerns about nanoscale TiO2 particles and their impacts on human health. The Healthy Building Network points to studies that have found TiO2 particles to be carcinogenic at the nano scale. This could be a concern for workers in manufacturing and construction and even in the use phase, when the particles may run off into water.
