ABSTRACT OF THE DISCLOSURE A washing water sludge from filtering systems, obtained through settling thereof, is disposed of by being introduced into a concrete mix as the mixing water for the preparation of concrete. The advantages of the present invention reside in the fact that developed for the first time is a method of util- ization of the washing water sludge of filtering systems, which formerly polluted the environment. The sludge has found useful application, and the strength properties of the concrete thus obtained are not only similar to those of the concrete made on a main water, but with a particular sludge composition are superior to them. The method is rather inexpensive to realize since it requires no special equipment.
