11/02/2018  titanium dioxide infused cement and placed into contact with polluted air. The concentration of nitrogen oxides varied from test to test, but the air was held at 80% humidity with a flow rate of 1.5 liters per minute. The test ran for 12 hours and recorded how much of the original concentration of nitrogen oxides was removed. Like before, a separate test took place with the

Cement and Concrete Research - COnnecting REpositories

In this work, a photocatalytic additive (titanium dioxide) was added to mortars prepared with aerial lime, cement and gypsum binders. The main goal was to study the way that microstructural changes affect the photocatalytic efficiency. The photocatalytic activity was determined using a reactor developed to assess the degradation rate with a common urban pollutant, NO x. The laboratory results ...

How to make concrete: PART 2b – Admixtures and

31/01/2014  Titanium Dioxide can be introduced to a concrete mix to form pure white concrete and create a self-cleaning and environmentally friendly concrete (by breaking down pollutants in the air). A fine example of concrete with a titanium dioxide addition is Richard Meiers’ Jubilee church outside Rome. Recycled mineral admixtures have also become popular as a concrete additive recently

The self-cleaning property is obtained by adding an additive to concrete which is called catalytic material which has a white color. An example of catalytic material is the titanium oxide as shown in Figure-1. Fig.1: Titanium Dioxide. Self-cleaning begins when this material is activated, and catalytic material activation will start due to energy that is received from sunlight (it also can be ...
