The present work analyzes a proposal for the reuse of water from fresh concrete returned to the ready-mix plants. This proposal is given through flocculating products, which will help clarify the concentrated water in the pools of the premixing industries. Likewise, the recovered water will have similar characteristics to the conventional water used, and which will subsequently enter the new concrete design, where it will contribute 5% in the strength of the additional concrete. On the other hand, the possibility of reusing the fines accumulated at the bottom of the ponds was analyzed, but these do not provide resistance to the concrete since the cement already hydrated; however, it can be used for other purposes. A qualitative and quantitative analysis of the economic, environmental and legal incidence was carried out; In the study of washing water, basic parameters (density by differential weighing, pH by pH metry, chemical composition) of three samples from different premixing plants have been analyzed to evaluate the quality of the discharges. Applicable solutions and technological improvements are proposed in the mixer washing process in order to reduce the volume of entrained solids, without disturbing the environment, and making it possible to save water. Finally, with the chosen flocculant and the results obtained, the economic optimization produced by this method for cleaning ready-mix concrete mixers will be analyzed.
