(57) Abstract: To obtain a cement-based hydraulic composition in which contents are dispersed and mixed sufficiently uniformly, an NOx purification function is improved, and storage stability is excellent. The system hydraulic composition is obtained by mixing cement clinker and titanium dioxide, and simultaneously pulverizing the obtained cement clinker mixture. The cement clinker mixture contains at least one of gypsum, slaked lime or an adsorbent, particularly activated carbon. These cement-based hydraulic compositions are kneaded with water and used as a cured product. |
