Innovative photocatalytic screeds and concrete admixtures.
Realization period:01.09. 2017 – 31.08. 2020
Leader at TUL:Mgr. Tereza Hulswit Sázavská, Ph.D.
The aim of the project is to prepare, in collaboration with BETOSAN Ltd., TUL, IIC, UFCH two types of products with photocatalytic properties.
The first type of product will photocatalytic active screed on cement-based application especially on concrete surfaces. The second type of product will photocatalytically active powder ingredient in concrete to allow preparation of concrete surfaces with photocatalytic function.
We assume to prepare two or more final version for both types of products. In the case of screeds the preparation of two colors white and gray is expected. We will prepare various types of dry mix concrete with respect to their application. This may be a type added to the entire volume of the concrete or only a surface part of the concrete for example. Especially the application of self-cleaning coatings on the exterior building shells is assumed, as well as the photocatalytic treatment of surfaces of various structures, e.g. bridges, noise barriers, guardrails, tunnels. Moreover there will be an additional contribution in the form of air cleaning. Prepared materials can be applied under certain conditions, even indoors where there is an important market, particularly in health care.
