Peruvian scallop valvs that are discarded in the fishery plants have potential as a raw material in the manufacture of construction materials, presenting themselves as an alternative to mitigate the negative environmental impact generated by their poor management. Pavers for pedestrian paving measuring 4x10x20 cm were manufactured under 3 mix designs using recycled aggregates from Construction and Demolition Waste (CDW) and aggregates from Peruvian Scallop Waste (PSW), with the aim of evaluating their mechanical properties, according to the 3 parameters required by NTP 399.611. The peruvian scallop shells to manufacture the aggregates were obtained from a processing plant located in Sechura, Piura, and were manually crushed until obtaining a granulometry in a range of 0.15 to 2 mm. A mix design was taken that uses only CDW aggregates developed by the company MP Recicla SAC (CICLO) as a base design, from which 3 mix designs were elaborated where the content of intermediate CDW aggregate was replaced by the aggregate of PSW obtained, in percentages of 20%, 40% and 60% respectively, keeping constant the content of cement, water and the fine aggregate of CDW. Granulometry tests were carried out on the PSW aggregate and compressive strength, water absorption and dimensional tolerance tests on the pavers, in accordance with the requirements of NTP 399.611. It was found that all the mix designs made under the conditions established in the investigation exceeded the minimum compressive strength value described in NTP 399.611, concluding that the PSW aggregate is viable to be used in the manufacture of pavers for pedestrian pavement.
