Abstract

This study investigates the physical and mechanical properties of concrete made with recycled aggregates, focusing on their reaction to acid attacks for sustainable construction in Cameroon. Despite initial challenges, such as lower density and higher water absorption in recycled aggregates, optimized concrete formulations can compensate, achieving comparable strengths to traditional concretes after extended curing periods. Recycled aggregates showed greater susceptibility to acid attacks, necessitating advanced protective strategies. Polynomial regression models enhanced the understanding of compressive strength evolution and degradation, proving vital for engineering predictions. The research advocates for the optimized use of recycled materials in construction, adhering to sustainability standards and contributing to environmental protection. Continued advancements in protective treatments and concrete formulations are essential for broadening the application of eco-friendly building materials.

优化混凝土耐久性：模拟耐酸再生骨料可持续建设在喀麦隆

本研究调查了用再生骨料制成的混凝土的物理和机械性能，重点研究了它们对喀麦隆可持续建筑酸攻击的反应。尽管最初存在一些挑战，例如再生骨料的密度较低，吸水率较高，但优化的混凝土配方可以弥补这一点，在延长养护期后，混凝土的强度与传统混凝土相当。再生骨料对酸的侵蚀表现出更大的敏感性，需要先进的保护策略。多项式回归模型增强了对抗压强度演化和退化的理解，对工程预测至关重要。该研究倡导在建筑中优化使用再生材料，坚持可持续发展标准，为环境保护做出贡献。保护处理和混凝土配方的持续进步对于扩大环保建筑材料的应用至关重要。

期刊介绍： Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics. Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences. Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
