SUMMARY:

The shellfish activity is the main source of income for many coastal communities, representing a historicalpractice dependent on natural conservation for sustainability. In Pernambuco, one extraction site is located in themunicipality of Igarassu, at the Santa Cruz Channel (Mangue Seco Beach). The biodiversity primarily consists of themollusk Anomalocardia flexuosa, generating a significant amount of waste, with shells accounting for approximately80% and meat for 20% in the adult phase. Proper disposal of these waste materials is challenging, leading to issuessuch as soil surface covering, vegetation loss, deforestation, river siltation, pollution from urban waste, and the spreadof disease vectors. To address these challenges, the technical and economic feasibility of incorporating shells for theproduction of 9x19x39cm concrete blocks will be analyzed. This involves replacing sand with crushed shells andgravel with ground shells, aiming to reduce the extraction of natural resources from quarries and sandbanks, whichare already scarce in large urban centers. Reference blocks (0%), along with those substituting at 25%, 50%, and100%, will undergo curing for 28 days, followed by tests for compression strength, water absorption by immersion(ABNT NBR-6136), drying shrinkage (ABNT NBR-6136), and capillary water absorption (ABNT NBR-9779).
