  ABSTRACT: This study investigates the effects of the partial replacement of cement (C) and sand (P) with rubber on the durability and mechanical properties of concrete under acidic environments. Results demonstrate that replacing sand with rubber in small percentages P (3%) improves acid resistance by approximately 2% due to rubber’s chemical inertness, while excessive replacement (for example, P (9%)) weakens compressive strength. Conversely, partial replacement of cement with rubber (for example, C (10%)) significantly reduces durability due to a decline in hydration products critical for strength. Among the tested batches, OP14 achieved the highest composite score of 0.848, balancing compressive and flexural strengths, low water absorption, and excellent durability. OP7 (composite score: 0.746) excelled in workability and strength, with moderate water absorption and durability, while OP13 (composite score: 0.691) offered exceptional durability but higher water absorption. The findings underline the potential of rubber-modified concrete for sustainable construction, recommending optimal proportions to achieve specific performance goals.
