Abstract

To address the scarcity of lime resources, this study explores the potential of using industrial solid waste, including fly ash (FA) and carbide slag, as replacements for lime or cement in soil stabilization for roadbed construction. The optimal mixing ratio of FA and calcium carbide slag (CCS) was determined using compaction and unconfined compressive tests. The study also examines the relationship between the optimum moisture content and the maximum dry density of the FA and CCS binder, as well as the strength variation trend. The study investigated the optimal mixing ratio of FA–CCS-stabilized soil, and the strength variation trend of FA and carbide slag-stabilized soil under different age and mixing ratios, using tests such as the unconfined compressive energy test, splitting strength test, compressive modulus of resilience test, and California bearing ratio test. Results indicate that the optimal mixing ratio of FA and CCS binder is 1 : 4, the advocated mixing ratio of CCS-stabilized soil is 8 : 92, and the excellent mixing ratio of CCS–FA-stabilized soil is 8 : 32 : 60.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
