Abstract
Official abstract text for this publication.
Provided herein is a cementitious composition comprising a photoactivator, wherein the photoactivator is capable of converting NOx to NO 2 — or NO 3 — when exposed to ultraviolet (U.V.) or visible light.
First claim
Opening claim text (preview).
1 . A cementitious composition comprising 15-25 wt. % of AFm and 0.001-5 wt. % of a photoactivator, wherein the photoactivator comprises doped TiO 2 and the photoactivator is capable of converting NO x to NO 2 − or NO 3 − when exposed to U.V. or visible light. 2 . The cementitious composition of claim 1 , wherein the photoactivator is capable of converting NO x to NO 2 − or NO 3 − when exposed to visible light. 3 . The cementitious comp…
