The objective of this research is to determine the axial compressive strength that replaces the fine aggregate with recycled PET at 5%, 10% and 15% in conventional f'c = 210 kg/cm according to NTP 339.034 CONCRETE (2008). For this study the aggregates of the quarry “Bazán“, Salida a Bambamarca at the height of the tap 3M and Portland cement type I, were used. The physicalmechanical properties of the used aggregates were evaluated. The values are presented: Module fineness 2.98, specific gravity 2.59 gr/cm 3 2 , absorption 0.911%, loose unit weight 1729 kg/m , compacted unit weight 1832 kg/m and moisture content 6.60% for fine aggregate, in the same way for coarse aggregate its fineness modulus is 6.99 , specific gravity 2.64 gr/cm 3 , absorption 1.64%, loose unit weight 1460 kg/m 3 , compacted unit weight 1526 kg/m 3 3 and moisture content 0.76%, complies with the specifications in ASTM C33-NTP 400.037. The concrete design was carried out using the ACI method of Committee 211 for a f'c = 210 kg/cm standard sample and 3 samples with different percentages of PET recycled 5%, 10% and 15% replacing the fine aggregate, evaluated in 3 Curing periods 7, 14 and 28 days; determining that after 7 days of curing the resistance reached was 144.38 kg/cm 2 with 0% recycled PET; 138 kg/cm 2 2 when replacing 5% PET; 131.13 kg/cm when replacing 10% PET and 123.39 kg/cm when replacing 15% recycled PET; after 14 days of curing the resistance reached was 181.23 kg/cm 2 2 with 0% recycled PET; 176.06 kg/cm when replacing 5% PET; 170.64 kg/cm 2 when replacing 10% PET and 164.91 kg/cm 2 2 when replacing 15% recycled PET; for a time of 28 days of curing the resistance reached was 211.21 kg/cm with 0% recycled PET; 204.72 kg/cm 2 when replacing 5% PET; 195.31 kg/cm when replacing 10% PET and 187.20 kg/cm 2 2 when replacing 15% recycled PET. Finally, it is concluded that the resistance to axial compression with respect to concrete, standard of the tests carried out, after 28 days of curing, decreases with the use of 5%, recycled PET at 5.28 kg/cm , with the use of 10%, recycled PET, decreases by 14.69 kg/cm 2 2 and with the use of 15% of recycled PET, with a decrease of 22.80 kg/cm ; evidencing that they decrease by 3.07%, 7.53% and 11.37% as the percentage of recycled PET increases by 5, 10 and 15% respectively.
