The included photocatalytic concrete paving material is marketed under the tradename TX Active. The second shoulder pavement element involved a similar, photocatalytic concrete material also containing the titanium dioxide additive, although in this instance the TiO2 was blended into a pervious (rather than conventional) concrete for the ...
In some embodiments the concrete treatment compound comprising the TiO 2 additive (or other photocatalytic compound) is sprayed or otherwise applied to horizontal road surfaces by a sprayer applicator with a spray bar of variable length utilizing industry standard nozzles.
The influence of additives such as H2O2, K2S2O8, Na2CO3 or NaCl, on the degradation efficiency of the dye in the presence of cement binder was systematically studied. Both Na2CO3 and NaCl were hindering the rate of photocatalytic degradation.
