In this paper, initial experiments were carried out to determine the possibility of using chicken feathers instead of sand in mortar. After earlier research suggested that chicken feathers had a high durability and resilience to degradation, chicken feathers recovered from slaughterhouses were chosen due to the significant cross-linking and strong bonding within their structure. Compared to natural sand, chicken feather sand (CFS) works as an eco-friendly resource. In this study, the chicken feather content ranged from 5% to 25% of the total volume of fine aggregates. The findings confirmed that the compressive strengths of the specimens are inversely proportional to the amount of feathers added. The specimen with 10% CFS had a compressive strength of 57.8 MPa after 28 days of curing. As the weight of CFS in the mortar increased from 1.26% to 10% of the control mixture, the workability significantly decreased. After soaking in water for 24 h, materials with higher proportions of feathers had a noticeably decreased compressive and flexural strength as well as increased water absorption and swelling. For 80% of the CFS replacement, the results are good. Additional CFS replacement tends to reduce the mortar weight. |
