Abstract

Edge-oxidized graphene oxide (EOGO) is a nano-sized material that is chemically stable and easily mixed with water due to its hydrophilic properties; thus, it has been used in various engineering fields, particularly for the reinforcement of building and construction materials. In this study, the effect of EOGO in soil reinforcement was investigated. When mixed with soil, it affects the mechanical properties of the soil-GO mixture. Various amounts of the GO (0%, 0.02%, 0.06%, 0.1%) were added into the sand-clay mixture, and their geotechnical properties were evaluated via multiple laboratories testing methods, including a standard Proctor test, direct shear test, compressibility test, and contact angle measurement. The experimental results show that with the addition of EOGO in soil of up to 0.06% EOGO, the compressibility decreases, the shear strength increases, and the maximum dry density (after compaction) increases.

摘要

边缘氧化石墨烯（EOGO）是一种纳米材料，由于其亲水性，化学性质稳定且易于与水混合；因此，它已被应用于各个工程领域，特别是用于增强建筑和建筑材料。在本研究中，研究了EOGO在土壤加固中的作用。当与土壤混合时，它会影响土壤 - 氧化石墨烯混合物的力学性能。将不同量的氧化石墨烯（0%、0.02%、0.06%、0.1%）添加到砂 - 粘土混合物中，并通过多种实验室测试方法评估其岩土工程性质，包括标准普氏试验、直剪试验、压缩性试验和接触角测量。实验结果表明，在土壤中添加高达0.06%的EOGO时，压缩性降低，抗剪强度增加，最大干密度（压实后）增加。
