SRM\u2013SC specimens were prepared with different types of slurry and rock contents based on an actual slurry injection ratio. The macroscopic level analysis involved measuring the specimens\u2019 uniaxial compressive strength and shear strength, determining the strength parameters, and analyzing the damage forms. At the microscopic level, the surface morphology and composition of the specimens were examined using scanning electron microscope imaging. This allowed for a comparative analysis of the cementation ability and mechanism of the slurry under different control conditions, providing a basis for determining the mechanical properties of SRM\u2013SC. The results indicated that the rock content significantly impacts the macromechanical properties of SRM\u2013SC. The compressive strength and stiffness of SRM\u2013SC initially increase and then decrease with the increasing rock content, with an inflection point observed between a 20% and 60% rock content. On the other hand, the shear strength and stiffness both increase with the increasing rock content. Additionally, the macroscopic mechanical properties of SRM\u2013SC formed by different types of grout exhibit noticeable differences. These findings serve as a reference for regulating the mechanical properties of SRM\u2013SC.<\/jats:p>","DOI":"10.3390\/ma18102186","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T08:20:23Z","timestamp":1746778823000},"page":"2186","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Cementation Mechanisms and Mechanical Properties of Different Soil\u2013Rock Mixtures\u2013Slurry Cements"],"prefix":"10.3390","volume":"18","author":[{"given":"Jiayong","family":"Li","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0050-3436","authenticated-orcid":false,"given":"Zuliang","family":"Zhong","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"National Joint Engineering Research Center of Geohazards Prevention in the Reservoir Areas, Chongqing University, Chongqing 400045, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"773","DOI":"10.1016\/j.conbuildmat.2018.09.098","article-title":"Three-dimensional observations of meso-structural changes in bimsoil using X-ray computed tomography (CT) under triaxial compression","volume":"190","author":"Wang","year":"2018","journal-title":"Constr.
