Abstract

In recent times, there has been growing interest in utilizing waste materials as coarse lightweight aggregates in the production of lightweight aggregate concrete. This approach has been gaining momentum as it has the potential to address the environmental concerns that come with conventional construction practices. The objective of this review paper is to evaluate the viability and potential of waste materials as coarse lightweight aggregates for producing lightweight aggregate concrete. This paper reviews the current research on various types of waste materials, including waste plastic, recycled concrete aggregate, slag, fly ash, and expanded polystyrene, as potential candidates for coarse lightweight aggregates. The paper highlights the properties and characteristics of these waste materials and their suitability for use as coarse lightweight aggregates. Additionally, the evaluation explores the mechanical characteristics of lightweight aggregate concrete that is generated using waste materials as coarse lightweight aggregates. Specifically, it compares the compressive strength, splitting tensile strength, flexural strength, and modulus of elasticity of lightweight aggregate concrete that includes waste materials with those of typical concrete. Furthermore, the paper discusses the sustainability benefits of using waste materials as coarse lightweight aggregates. By using waste materials in construction, not only are resources conserved, but waste is also diverted from landfills, reducing the negative impact on the environment. In conclusion, this review paper demonstrates that the use of waste material as coarse lightweight aggregate for lightweight aggregate concrete production is a viable and sustainable approach. The application of waste materials as coarse lightweight aggregates in lightweight aggregate concrete demonstrates mechanical characteristics that are similar to traditional concrete. Moreover, utilizing waste materials in this manner provides environmental advantages. This study offers valuable insights into the implementation of waste materials in construction, and it emphasizes the possibility of further exploration and advancement in this domain. For this review, a total of 15 articles were analyzed, with publication dates ranging from 2005 to 2021. The study contributes to several Sustainable Development Goals (SDG 9/11/12/13) set by the United Nations such as providing insights into the role of industry, innovation, infrastructure, sustainable cities, responsible consumption, production practices, and climate action.
废料作为轻质混凝土生产粗集料的潜力:一种可持续的方法
近年来,人们对利用废料作为粗轻骨料生产轻骨料混凝土越来越感兴趣。这种方法已经获得了动力,因为它有可能解决传统建筑实践带来的环境问题。本综述的目的是评价废物作为粗轻骨料用于生产轻骨料混凝土的可行性和潜力。本文综述了各种类型的废物,包括废塑料、再生混凝土骨料、矿渣、粉煤灰和膨胀聚苯乙烯,作为粗轻质骨料的潜在候选材料的研究现状。重点介绍了这些废料的性能和特点,以及它们作为粗轻质骨料的适用性。此外,评估探讨了轻骨料混凝土的机械特性,这种混凝土是用废料作为粗轻骨料制成的。具体来说,它比较了包括废料的轻骨料混凝土与典型混凝土的抗压强度、劈裂抗拉强度、抗弯强度和弹性模量。此外,本文还讨论了利用废料作为粗轻质骨料的可持续效益。通过在建筑中使用废料,不仅节约了资源,而且废物也被转移到堆填区,减少了对环境的负面影响。综上所述,本文综述表明,利用废料作为粗轻骨料生产轻骨料混凝土是一种可行的、可持续的方法。在轻骨料混凝土中应用废料作为粗轻骨料,表现出与传统混凝土相似的力学特性。此外,以这种方式利用废物具有环境优势。本研究为废弃物在建筑中的应用提供了有价值的见解,并强调了该领域进一步探索和发展的可能性。本综述共分析了15篇文章,发表日期从2005年到2021年。该研究为联合国制定的若干可持续发展目标(SDG 9/11/12/13)做出了贡献,例如为工业、创新、基础设施、可持续城市、负责任的消费、生产实践和气候行动的作用提供了见解。
