It seems the active ingredient in rice soup was used to make the mortar to bind rocks in the making of walls and buildings and now they figured out the exact reason. It also seems like a sure bet for individuals around the world to make sure their own walls last as long as the Chinese ones since rice soup is so cheap.

I see from the article, that the main ingredient is lime - as in cement. So why would the resulting mixture be easier and cheaper to manufacture than cement?
I also suspect is it not as strong as cement. The only comparison they give is with traditional lime mortar.
I have lived in houses in Livingstone built with lime mortar. It works quite well if kept dry. It isn't nearly as strong as cement though.
