Concrete Photocatalytic Activity Test

[@julianfedak6126]

What is compound is being used?..

[@Fredricjakobsen]

Hvist jeg spraier dette på vei skilt blander det inni folien på veibaneskilt vill da skiltene da rense luft?

[@Fredricjakobsen]

Adam kann mann lage stråle sikker hus maling så norr du maler huset ditt så stopper radiobølger og telefon bløger på husveggen? Hville noen kjøpt slik maling?

[@Fredricjakobsen]

Er dette helt jenomsikkti stoff kann det da blanne inni deksel til mobil telefoner så renser mobiltelefon dekslet luft? Kann mann da også lage ett slikt produkt som blandes i selve skjermen på mobil telefoner så blir telefonen selvrensende?

[@Fredricjakobsen]

Funderer dette stoffet som konsiler du spraier dette på betong vegger og så kommer det graffity mensker med spray bokser og sprayer på betongen så kann du enkelt fjerne grafity med og vaske med høytrykspyler?

[@Fredricjakobsen]

Du er vell i Danmark eller Oslo hvist du spraier dette på betongen inni alle tuneller i Norge vill da luften inni tunnelene bli renset? Hvist du spraier dette på betongen Storo og Sinsen krysset på synlige betong flater vill da dette rense luften?

[@Fredricjakobsen]

Kann mann bruke dette kjemikaliet i selve betongen på betong blande stasjoner hvill da hele betong veggen da rense luften? Nor betongen er vanntett?

[@Fredricjakobsen]

Så hvist EU og bygge industrien setter dette som krav alle hus skall ha slikt tak spraiet på apsolutt alle hustak innenfor EU sine grenser for og forbedre luftkvaliteten må da alle huseiere kjøpe eller bestille dette produktet. Da?

Sir only titanium oxide exhibit the photocatalytic property? What about nano zinc oxide and nano magnesium oxide... Do they adsorbed gaseous pollutant.?

[@johanedduque]

Extremely interesting, I make concretes with waste ash which have a great percentage of TiO2, I would like to test if they break down pollutants, how did you test it? thanks

[@photocatas552]

You need to find a lab that does ISO 22197-1 tests and send them a sample. However, not all TiO2 will give you the effect, which is why we have worked a lot to develop a high quality TiO2 based photocatalytic dispersion. Most likely, your TiO2 is rutile and not anatase - so it won't have the photocatalytic effect. en.wikipedia.org/wiki/Anatase

[@johanedduque]

@@photocatas552 Thank you very much, this is a fantastic information. It is extremely difficult to assess the type of TiO2 in the Waste ash because we don't know what material was burnt. We have to test it. I will do so in Canada next year at the NRC.

[@photocatas552]

@@johanedduque- Sounds good. FYI we produce and sell a concrete sealer with the photocatalytic feature. photocat.net/wp/products/photocat-garden/

[@abdultabrez]

@@photocatas552 As said photocat garden requires 1L for 8m2 of area.. what is the efficiency of No2 getting adsorbed on the surface.

[@Fredricjakobsen]

Vorfor komm jeg på deg akkurat nå Adam?

[@Fredricjakobsen]

Tv spill konsoller?

[@dishantvora2416]

Hello Sir, Which material is used in this concrete and where can i find it

[@Fredricjakobsen]

Er dette stoffet brannfarlig hvist du spraier det på taket på ett bygg? Vilken brann sertefisering er det på dette produktet?

[@musafirization_]

what is the mineralization efficiency?

[@arniedelacruz6274]

what chemicals were used as indicator in this vid??

[@Fredricjakobsen]

Plutselig var du inni min jerne hvorfor?

[@pasalman3474]

hello sir, i am a final year btech student in civil engineering.Our project is self cleaning concrete,so what is the name of the machine to determine the photo catalytic action of concrete ? i hope you will complete my doubt..

[@photocatas552]

We test according ISO 22197-1

[@karlohorvat8810]

What is that blue liquid?

[@nirmalsuthar9264]

Methylene blue

[@dhruvilsodagar6661]

how to determine absorbed pollution amount..?

[@photocatas552]

Great question. We perform a variety of tests in our lab and on reference cases out in the built environment to assess the actual amount of NOx we can degrade and do degrade. Feel free to check out our website (www.photocat.net) or give us a call :)

[@miguelv4345]

What kind of light were you using?

[@lucifermorningstar323]

UV

[@meetshah35]

Sir actually we have been doing research on photocatalytic concrete since last 1 year so we have certain doubts regarding to it...is there anyway to contact you? Kindly revert. ~From India
