Assessment of the Optimal Ratio of By-product Slag or Traditional Crushed Aggregate in a Replacement Mixture for Soft Soil Improvement and Optimal Replacement Thickness

Guest Editorial to the Special Issue: Novel Technologies for Grouting, Jet Grouting and Soil Deep Mixing

“…A non-homogeneous combination of cement and soil throughout the operation, a change in the curing conditions between laboratory and field operations (such as temperature and humidity), or machine operation are some examples of the discrepancies between laboratory and field conditions that lead to errors, considering that it is impossible to replicate all the in-situ conditions of intact soil in laboratory compacted soil specimens. Ali (2022) starts from the case study of a failure in Alexandria (Egypt) caused by an excess store load and compares Steel Slag Coarse Aggregate and Traditional Crushed Stone Aggregate in replacement mixtures with different mixture ratios and thicknesses. This study adopted a top replacement mixture layer with different mixture ratios and thicknesses to optimize these parameters based on experiments.…”
