Self-cleaning concrete is made by employing nano-titania particles in concrete.
Dear Sir,
You may perform following test :
1. International Standard ISO 22197-1 “Fine ceramics (advanced ceramics, advanced technical ceramics) – Test method for air-purification performance of semiconducting photocatalytic materials,” which is adapted from the Japanese Standard JIS TR Z 0018 “Photocatalytic materials – Air purification test procedures.”
2. Photocatalysts
You may use the Rhodamine test (Rh-B) according to UNI 11259: 2008 (Determination Of The Photocatalytic Activity Of Hydraulic Binders)
Concrete photocatalytic
activity index test using a simple digital scanner and an indicator ink, suitable for use in the laboratory, or in the field, for assessing the photocatalytic activity of commercial photocatalytic self-cleaning materials such as glass,
