In different parts of the world such as England, Cuba and Peru, a situation is occurring in which the raw material for construction such as aggregates is running out due to overexploitation and there is fear in the future that there will be a greater criticality of these materials. Therefore, the objective of this study is to elaborate a concrete f'c = 210 kg / cm2 for vertical elements, in order to partially reduce the cement by rice husk ash (CCA) and the sand by PET. In this investigation, it has been determined that the incinerated rice husk can cause the material to behave like a pozzolana just like cement. Likewise, in the case of recycled PET, it has been investigated with a reduced size that can allow it to adhere and accommodate in a better way, avoiding generating gaps in the concrete. In this research, four combinations with different proportions of CCA and PET have been elaborated, of which two of them have presented favorable results, meeting all the technical requirements for a concrete f'c = 210 kg / cm2. This proposed concrete can reduce the use of cement and 2.5% sand for one cubic meter of concrete by 10-15%. In this way, it has been shown that the use of agro-industrial material such as rice husk and recycled material such as PET can reduce the use of aggregates such as sand, limestone and clay, the latter by up to 6%. They are used to make cement.
