**5. Conclusions**

The paper presents a new possible method of hydromixture transportation in pipelines, enabling significant energy savings in such transportation. This effect was achieved by using an additive of deflocculant, whose composition was self-developed and contains environmentally neutral mineral particles. The proposed method, except for the energy savings, reduces the amount of water used in such transportation, thus reducing the amount of burdensome slurries, which is an additional ecological aspect of the proposed method.
