This project aims to analyze the effects of the reuse water from the washing of concrete mixer trucks of the concrete dosing station studied, as to the mechanical strength of the machined concrete in its fresh and hardened state. In addition to checking how influences as to the plasticiser additive process, also used by the center. The method used to the analysis the compressive strength of the concrete by reproducing the trace, for the molding of the specimens, through the comparison between a standard trace and samples of different proportions of kneading water, reused and potable and plasticiser additive, based on the trace used by the metering station. The results obtained with the laboratory tests were different due to the different combinations. The results showed the viability of the reuse of the washing water of the trucks for the formulation of a new trace of concrete, without any treatment of this water being necessary. In addition, it does not present any interference in the compressive strength of this new trace. Also, the concrete obtained a good workability in the traces which the plasticizing additive was present, and consequently increased its mechanical resistance, which necessitates the addition of this additive.
