The present investigation was carried out in the city of Trujillo, the influence of porcelain waste as a replacement for aggregates in concrete was analyzed, which were included in percentage terms simultaneously with a gradation similar to that of each replacement aggregate and in addition, tests were carried out to evaluate compressive strength, indirect tensile strength, resistance to chloride ion penetration and porosity for further analysis. The purpose of the research was to determine the influence of porcelain residues on mechanical properties and durability in concrete with plasticizer in Trujillo 2023, for which initially the characterization of natural aggregates such as crushed porcelain and ground porcelain was performed. It was observed that the porcelain is more suitable for the manufacture of concrete; in addition the resistance of the concrete was defined (f'c=210 kg/cm2 or 20.60 MPa), under the method ACI 211 for the mixing design, however, it had to be optimized, resulting in the following proportions in weight: Type Ico cement (18.5 %), sand with 2.7 (41.0 %) fineness modulus, 1/2' minced stone (29.8 %), mixing water (10.4 %) and SikaCem plasticizer additive type A with a constant dosage of 0.7 % depending on the weight of the cement. From the optimized design, the respective replacements in the coarse aggregate and fine aggregate by crushed and ground porcelain were made in percentages of 5 %, 10 %, 15 %, 20 %, 25 %, 30 % and 35 % with respect to the weight of natural aggregates. All the results of the properties evaluated were favorable; the maximum percentage of replacement of aggregates by crushed and ground porcelain was 35 % for each aggregate, initially obtained in the standard specimen 268 kg/cm2 (26.28 MPa) in compressive strength, 19 kg/cm2 (1.86 MPa) in indirect tensile strength, 6352 Coulombs in the past load of the RCPT test indicating high penetrability to the chloride ion and 21.2 % volume of voids, improved to 347 kg/cm2 (34.03 MPa) in compression strength, 32 kg/cm2 (3.14 MPa) in indirect tensile strength, 2078 Coulombs in past load of RCPT test indicating moderate chloride ion penetration and 16.7 % vacuum volume. Likewise, a unit cost analysis was carried out, proving the feasibility of manufacturing concrete with porcelain additions to replace each aggregate, not only for the economic impact but also for the environmental impact.
