Mechanical Bearing Performance Cement–Fly Ash Project Details
| Abstract |
The purpose of this study is to determine the effectiveness of cement-fly ash mixtures when used to improve the engineering characteristics of clay soils, when used for subgrade purposes in areas where moisture is a concern. This study attempts to solve the problem of low bearing capacity of clay soils affecting the performance of road pavement subgrade. Laboratory tests were performed to determine the potential of fly ash to stabilize a soil sample containing 0%, 5%, 10%, 15%, and 20% of fly ash and a constant amount of cement. The set of stabilized soils was tested for Atterberg limits, compaction, and California Bearing Ratio (CBR). The results show that cement-fly
ash mixtures negatively affect soil plasticity and increase the maximum dry density and bearing capacity of the soil. The highest mechanical improvement was achieved with 15% fly ash, as well as the highest improvement of CBR values over untreated soil. In contrast, when fly ash was increased beyond 15%, the rate of improvement in bearing capacity was significantly reduced. The study identifies the best cement-fly ash mixture that improves clay subgrades and uses materials efficiently. The findings advance sustainable pavement design and the use of by-products of the industry, thus supporting the Sustainable Development Goals, particularly SDG 9 (Industry, Innovation and Infrastructure) and SDG 11 (Sustainable Cities and Communities).
