Composition for preparing precast concrete and cement derivatives with bactericidal and fungicidal properties, precast concrete containing it and preparation process thereof

摘要

The present invention relates to a composition for cement derivatives and precast concrete, precast concrete containing it and preparation process thereof. The composition of the invention has biocidal effects both in the presence and absence of light, including organometallic components of different natures that are active under normal atmospheric conditions. Therefore precast the invention can be used both inside and outside of buildings and public spaces and at both locations are able to reduce and / or eliminate bacteria, molds, allergens and other microorganisms.
