Solid wastes are increasingly used to stabilize marine soft clay. Disposals of alkali slag and steel slag cause serious problems in Lianyungang City. These two waste materials are used to produce the compound cementitious material by mixing with GGBS, replacing the cement to treat the soft clay in Xuwei Port. The raw materials are collected from fields. The orthogonal test is performed to investigate the unconfined compressive strength (UCS) of the treated soil. The influence of alkali slag-soft soil (SR-S) ratio, the steel slag-GGBS (SS-GGBS) ratio, the curing agent, and the curing time are considered, followed by the investigation of reaction mechanisms. The optimal mixing ratio is recommended when the SR-S ratio is 1:1 and the curing agent content equals 10%. A well-documented dataset is developed by summarizing 1069 data of UCS from the literature. A PSO-BP-NN model is developed using the collected data and the experimental data so that generalization is guaranteed. The model is feasible to predict the UCS of treated soil by considering characters of the material properties and experimental techniques. This study aims to provide a reference for initially determining the mixing ratio of cementitious materials at field treatments. [ABSTRACT FROM AUTHOR] |
