چکیده مقاله
Photocatalytic self cleaning is one of the most important applications of nanotechnology in the construction industry Natural and industrial pollutants such as NOx, carbon monoxide, VOCs, chlorophenols and aldehydes from automobiles and industrial effluents are degraded by photocatalysts with the help of highly active catalyst titanium dioxide nanoparticles Self cleaning concrete containing titanium dioxide has the property of increasing the percentage of associated water absorption The use of nanosilica with titanium dioxide can eliminate this defect In this paper, the effect of using nanosilica and titanium dioxide on the water absorption percentage of exposed precast concrete components in the architectural view of concrete structures has been investigated In this paper, the effect of using nanosilica and titanium dioxide on the water absorption properties of concrete is investigated Four designs were tested with zero, 2 5, 3 5 and 5% replacement of cement with TiO2, each with 2% nanosilica percent adsorption percentage Reducing the water absorption between the designs of the studied mixtures shows the positive effect of TiO2 in reducing the water absorption on the concrete surface An increase of titanium dioxide up to 3 5% leads to a decrease in water absorption in the samples but An increase of titanium dioxide up to 5% leads to a increase in water absorption in the sample This is due to properties of titanium dioxide for higher percentages for increasing the percentage of associated water absorption Using of titanium dioxide higher than 3 5% can be caused in increasing the percentage of associated water absorption
