Scientists in Austria and Norway have discovered how silicate nanoparticles can save historic buildings made of porous rock from deteriorating in adverse weather.

Constructions made of porous rock may weather over time. TU Wien (Vienna) researchers have now thoroughly examined how silicate nanoparticles can help save them for the first time.

Buildings made of porous rock can weather over the years. Now, for the first time, scientists at TU Wien (Vienna) have studied in detail how silicate nanoparticles can help save them.
