Cement-stabilized large-sized steel slag base course based
Currently, cement-stabilized SS mixtures are more often formed by SCM, and there is an acute lack of valuable research on cement-stabilized large-sized steel slag (CSLS) mixture based on VCM. Therefore, this paper analyzes the factors affecting the mechanical properties of vibration-formed CSLS mixtures, wherein parameters such as The cement–TDA-stabilized SC–GR at SC:GR of 90:10, cement content of 2% and TDA content of 2% is suggested as a sustainable subgrade material.

Hydraulically Bound Mixture an overview ScienceDirect
Case studies dealing with the use of RCA and MRA in hydraulically bound mixtures (HBMs) with a cement content between 3% and 8%, mostly used in base layers, are given in Table 13.9. The majority of the HBMs were made with RCA with a maximum aggregate size above 38 mm and only in one case was the HBM made with MRA. Table 13.9.Cement-stabilized macadam (CSM) is a family of compacted blends containing aggregates with appropriate grading, cement of 3–8% by weight of aggregates and water at optimum moisture content Mechanical Properties of Sandstone Cement

Materials Free Full-Text Evaluating Cement Treated
To further compare the environmental impacts of cement-stabilized aggregate with steel slag in the aspect of equivalent CO 2 (CO 2eq) emission, life cycle analysis (LCA) models of cement-stabilized aggregate base course were prepared with SimaPro 9 software. The methodology of LCA consists of 4 stages including goal and Cement-stabilized aggregate mixture (CSAM) is a typical semi-rigid base material, which is a kind of heterogeneous material with low cement dosage. It is easily causes segregation, crushing, loosening and other defects in the mixing, transportation, paving and rolling stages, but improving the uniformity of the mixture can solve these Study on the Properties and Mechanisms of a Cement-Stabilized

Research on macro-microscopic mechanical evolution mechanism of cement
It can be seen from the diagram that the cement-stabilized material is composed of aggregate, cement matrix and interfacial transition zone (ITZ). Compared with aggregate and cement matrix, ITZ has larger void, higher porosity and loose structure, so it is the weak area of cement-stabilized material.

Strengthening mechanisms in cement-stabilized kaolinite
The macroscale mechanical properties of cement-stabilized soil have been widely reported, but the microscale behavior remains largely unexplored. This paper presents the first attempt to reveal the microscale strengthening mechanisms in a cement-stabilized kaolinite via big data cross-scale nanoindentation coupled with X-ray The resulting mix is an extremely compacted mix of cement and soil, sometimes referred to as a “cement-stabilized base” and sometimes a “cement-treated aggregate base”. When the cement undergoes hydration, the resulting material is hard and long-lasting. This process of cement stabilization must be done during the compaction Overview of Soil Stabilization Methods in Road Construction
