摘要

保持稿件所需格式的最佳方法是用其正文覆盖这些说明。论文应以英文撰写。手稿 s 垃圾填埋是印度最常见、最廉价的废物管理方法。城市固体废弃物填埋场(MSWL)已成为影响周边地区健康、卫生、环境和美观的公害。骨料几乎占混凝土的 70%,因此用骨料代替废料可能是一个有益的选择。在目前的工作中,正在进行一项实验调查,以测试在混凝土生产中添加 MSWL 作为细骨料的替代品。根据基本物理性质,从垃圾场现有的不同陈化样本中,选择陈化程度最高的样本进行实验研究。用 0%、4%、5%、7% 和 10%的城市固体废物部分替代细骨料的混凝土混合料进行了机械性能测试,如抗压强度、劈裂拉伸强度、抗弯强度和无损测试,结果证明可以部分替代细骨料。吸水性、酸侵蚀和硫酸盐侵蚀等耐久性研究也为这种废料的可持续再利用提供了更好的实验证明。研究表明,考虑到所有测试结果值,5% 的替代率是最佳的。这篇论文有助于对该材料在建筑行业的适用性进行深入研究。

Mechanical and Durability Studies about the use of Municipal Solid Waste Landfill in Concrete
The best way to keep the required format of the manuscript is to overwrite these instructions with its text. Papers should be written in English. Manuscripts s Landfilling is the most common and cheapest method of waste management practice in India. Municipal Solid Waste Landfills (MSWL) became a nuisance affecting the health, hygiene, sanitation and aesthetics of the surrounding area. Aggregates occupy almost 70% of concrete, so replacing waste materials with them could be a rewarding choice. In the current work, an experimental investigation is being carried out to test the addition of MSWL as a substitution with fine aggregate for concrete production. Out of the different aged samples available at the dumpsite, the most aged sample is chosen for experimental investigations according to the basic physical properties. Concrete mixes, with 0%, 4%, 5%, 7% and 10% partial replacement of fine aggregate with MSWL are tested for mechanical properties such as compressive strength, split tensile strength, flexural strength, and non-destructive test and have proved to be a partial substitute for fine aggregate. Durability studies such as water absorption, acid attack and sulphate attack also gave better experimental proof for the sustainable reuse of this waste material. The research reveals 5% replacement is the optimum considering all the test result values. The paper leads to advanced research for the suitability of the material in the construction industry.
