08/11/2022TP has been widely studied as an artificial aggregate [ 8, 9, 10 ]. Tuff is a stone formed from volcanic ash that contains pozzolanic material that reacts with calcium hydroxide (CH) to form calcium silicate hydrate (C-S-H) gel. The Al content in tuff is high, and can be dissolved and fixed in cement hydrates.
