Rapid SetThe primary ingredient is Calcium , the melting point is 2700 F.... Rapid SetI fixed the link for you. "http://" was in there twice. FYI When pasting a link into the "Create Link" tool, "http://" is already there by default. Even though when you copy an address to post a link, "http://" is included in the address you copied. When creating a link, you can either delete it before pasting or paste over it while it is selected, but clicking next to it before pasting (so the default "http://" is no longer selected) will result in an extra "http://". Seems unnecessary for it to be there by default.

Thank you David! I also wrote calcium when I meant calcium sulfoaluminate...
Perhaps that changes things. Karl?

Calcium Sulfoaluminate 40 - 50% Limestone (calcium carbonate) 40 - 50%

Huh. It lists the melting point as 2700 F. I wonder if the calcium carbonate acts the same way that perlite acts in some of the geopolymer mixes that you have previously described.

Karl-Rude much? Read the entry,when you first posted. It does not explain why the products listed melting point is so high. Since I didn't understand I asked a question based off what I had gleaned from your geopolymer thread. If I knew the chemistry for myself I am sure the explination would be obvious. Next time be a little more lazy if you have nothing nice to to say . Nothing is f Jun orcing you to respond at all.

The melting point of quicklime is 2613 °C, 4735 °F Yep, but isn't quicklime, not anymore quicklime after it's been wetted? So back to 840C° for chalk or not? Or the influence of the other materials have made it tougher regarding heat? They say melting point is 2700F° 1480C° ney bad!
