<P>PROBLEM TO BE SOLVED: To provide a composition which is hardened without deteriorating the performance of a photocatalyst, lowering the workability and necessitating special aging even at low temperature so that the construction period can be shortened and to provide a structure formed by using the composition. <P>SOLUTION: This photocatalyst carrying composition contains a hydraulic material, a fine aggregate, a setting modifier, a water reducing agent and a material having the performance of the photocatalyst. Calcium aluminate other than C<SB>3</SB>A (tricalcium aluminate) is incorporated in the hydraulic material by ≥8 wt.%. In particular, it is preferable to incorporate lithium carbonate and tartaric acid as the setting modifier. <P>COPYRIGHT: (C)2004,JPO |
