Reviewer 2 Report
The paper concerns the important issue of the combined effect of calcium chloride and cement on expansive soil materials. A laboratory investigation was carried out to investigate the effect of the addition of calcium chloride with cement on the swell potential, swell pressure, compression index, suction, and unconfined compressive strength. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX) testing was conducted. X-ray diffraction patterns were recorded to observe the mineralogy of the material. The results confirmed that calcium chloride with cement is very effective for stabilizing the expansive soil. A reduction in the swell potential by 8% and 25% and a reduction in swelling pressure by 28% and 37.4% were observed for 4% and 8% calcium chloride with cement addition. The compression index decreased with the increase in the calcium chloride content.
The abstract should show what has been carried out and what is novel of the work. Please indicate the novelty of the paper in the introduction, and if possible highlight it clearly in each part of the manuscript. What are the advantages and limitations of the proposed method? Please indicate the novelty of the paper in the introduction, and if possible highlight it clearly in each part of the manuscript. Is possible presents the discussion to illustrate the limitations, pitfalls and practical difficulties of applied methods. Please provide any insights on the accuracy performance, comparing with other models, verification metrics, evidential analyses, any limitation of this work. The literature review are shallow. since the given results only uncovers the samples and won't determine what variables have the most influence, therefore, extraneous variables might interfere with the information and thus outcomes can be adversely impacted by the quality of the work. When you have different involved parameters definitely sensitivity analyses and model calibration must be carried out to show their influence on the results. The general framework of the presented study should be presented. Manuscript should be prepared taking into account the paper guidelines.
