Prediction of Unconfined Compressive Strength of Fly Ash–Soil–Lime–Fiber System Using Multiple Regression Analysis
This study reports the development of the prediction models using multiple regression analysis for predicting the unconfined compressive strength (UCS) of fly ash–soil–lime system reinforced with polypropylene fibers. The results obtained through laboratory UCS tests on different combinations of the fly ash–soil–lime–fiber system are utilized for the development of the models using SPSS software. The mixes of fly ash stabilized with 15 and 25% of soil, 10, 15 and 20% of lime contents and polypropylene fibers having 0.1, 0.2 and 0.4% were prepared and tested for their strength at curing periods of 7 days and 28 days. Six prediction models are developed. Further, the developed models are validated by using 12 laboratory trial mixes. The UCS values predicted by using these models are found to be in fair to better agreement with the actual values of UCS obtained by the laboratory results.
