I believe Mortar does have lime in it just like concrete does.
Are there any other options ?

Ok so portland bad... Motar ?
Also I didnt see any other possibilities with those links.. maybe I missed something

Ok
so I am new here and new too the whole Mass heater idea... Now i have watched the videos by Permies.com. I have noticed that most mass heaters are made from Cob. Now can one be made and use mortar or portland?
I do not have any clay in my area i barely have any dirt at all ..lol I need to know what other possibilities there are available too me.
Thanks Daren
