In this research work conducted in the city of Trujillo, the influence of recycled porcelain in Type II cobblestones is studied as a replacement for fine aggregate in its physical and mechanical properties such as absorption, density, compressive strength, and flexural strength. The physical and mechanical properties of concrete have been extensively studied in recent years, as they are crucial for the development of cobblestones in this research. However, in efforts to enhance these properties, new products have been introduced, primarily by replacing one of its components with recycled materials. There is a substantial amount of porcelain waste from construction projects that ends up in various landfills, posing significant risks of soil and water contamination on a large scale, thereby also presenting socio-economic risks. The objective of this research was to determine the optimal percentage of fine aggregate replacement with recycled porcelain that yields the best results in absorption, density, compressive strength, and flexural strength for Type II cobblestones with a target strength of 420 kg/cm2. To achieve this, recycled porcelain percentages of 0 % (control), 15 %, 30 %, 45 %, 60 %, and 75 % were assigned fortimax cement from Pacasmayo, type MS, was used, with coarse aggregate having a maximum nominal size of 3/8", and the fineness modulus of the fine aggregate was 2.9. For 1 m3 of mixture, the composition used was 623.49 kg of cement, 199.52 kg of water, 727.08 kg of fine aggregate, and 705.78 kg of coarse aggregate. For the formation of the cobblestones, a hydraulic press was used at a pressure of 6 tons for one minute. A total of 54 samples were prepared with dimensions of 10 cm x 20 cm x 6 cm, following the NTP 399-611 standard. The concrete cobblestones were tested after 28 days of curing in water and lime. The optimal replacement percentage was found to be 30 %, where the following properties were observed: an absorption value of 3.65 %, representing an 11 % increase compared to the control sample; a density of 2260 kg/m3, which is 2 % lower than the control sample; a compressive strength of 519 kg/cm2, marking a 22 % increase compared to the control sample; and a flexural strength of 73 kg/cm2, also showing a 22 % increase compared to the control sample.
