This article presents an experimental study to analyze the mechanical properties of a soil stabilized with ordinary Portland cement (OPC) under a sustainable approach consisting of a significant substitution of OPC for sugarcane bagasse ash (SCBA) to reduce the quantity of cement used in the stabilization, reaching the necessary mechanical requirements for its use as a subgrade layer. Soil specimens were elaborated with 3%, 5%, and 7% OPC as a stabilizing agent by weight of the soil. These mixtures were then partially substituted with 25%, 50%, and 75% SCBA, with these percentages being by weight of the stabilizer (OPC). Compaction, compressive strength, and California bearing ratio (CBR) tests were performed to evaluate the mechanical properties of the specimens. The results indicate that a 25% substitution of OPC by SCBA shows a similar performance to the mixture with only Portland cement, so a reduction in OPC use can be made. Further, with a substitution of 100% OPC by SCBA, the CBR of natural soil without stabilizers is improved.
本文介绍了一项实验研究，旨在分析在可持续方法下，用普通硅酸盐水泥（OPC）稳定的土壤的力学性能。该可持续方法包括用甘蔗渣灰（SCBA）大量替代OPC，以减少稳定化过程中水泥的用量，同时达到用作路基层所需的力学要求。通过将3%、5%和7%的OPC作为稳定剂按土壤重量添加来制备土壤试样。然后用25%、50%和75%的SCBA对这些混合物进行部分替代，这些百分比是相对于稳定剂（OPC）的重量。进行了压实、抗压强度和加州承载比（CBR）试验，以评估试样的力学性能。结果表明，用SCBA替代25%的OPC表现出与仅含波特兰水泥的混合物相似的性能，因此可以减少OPC的用量。此外，用SCBA 100%替代OPC可提高无稳定剂天然土壤的CBR。
