    • The invention relates to a method for producing coloured concrete bodies, particularly coloured concrete roof tiles, whereby pigment is added to the unprocessed concrete mix. In order to provide a method which makes possible the production of permanently coloured concrete bodies with reasonably priced pigments which are stable in outdoor exposure and are resistant to light, particularly UV, alkalis and heat, it is proposed that a cement compatible aqueous polymer dispersion in which organic pigment is dispersed be added to the unprocessed concrete mix. Suitable cement compatible polymer dispersions are aqueous polymer dispersions based on styrol and/or pure acrylate. Phthalocyanine or China acridon pigments are particularly suitable as organic pigments.
    • 本发明涉及一种生产有色混凝土体,特别是彩色混凝土屋顶瓦的方法,其中将颜料加入到未加工的混凝土混合物中。 为了提供一种方法,可以生产具有价格合适的颜料的永久着色的混凝土体,其在户外暴露中稳定并且耐光,特别是耐紫外线,碱和热,所以建议将水泥相容的水性聚合物分散体 将有机颜料分散在未加工的混凝土混合物中。 合适的水泥相容聚合物分散体是基于苯乙烯和/或纯丙烯酸酯的水性聚合物分散体。 酞菁或中国吖啶颜料特别适合作为有机颜料。
