Is rice soup 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.
