No. Cement gains strength from absorbing water and forming hydrate compounds. Above a certain temperature, those hydrates lose their water content, which then flashes to steam, sometimes explosively. 

I see that this was your first post on IFI. Welcome, but please READ THIS FIRST!!!

Thanks, I’ll get on the things in the read this first section! I’ll steer clear of the cement then, just asking because I am just starting out and making a forge out of an old stainless steel keg and I am needing to line it. Here’s a pic of part way in (if anyone is interested haha) 

I am not sure if I missed this but when making your own clay, what are your thoughts on mixing the bentonite (cat litter) with sand and cement. Would the cement hold it together in a similar fashion to some straw?
