ceramic castaways, as well as bricks, can be used to make a cement that's just as strong as traditional cement, but through a process that's much less dirty.
A more shocking revelation is that another waste material is used as an activator. According to Treacy, rice husk can be used instead of sodium hydroxide, sodium silicate, meaning it is such an economical process that minimizes on costs and environmental damage. This type of cement is even much stronger than normal cement...wow! Great one there, and everyone is on the know.
