“…The same behavior of the expansive index was observed by Ali et al [26]. Sol-Sánchez et al [27] found that dolomitic lime from residual sludge was effective as a stabilizing addition to clayey and marly soils due to the increase in pH values, carbonate content, and particle size distribution of the mixed soil when this binder was added. Sivrikaya et al [23] reported a decrease in Atterberg limits and an increase in the maximum dry unit weight of the compacted mixed soil when marble waste powder was added to an artificial clayey soil.…”

The natural stone industry generates large amounts of industrial waste every year. Limestone powder produced by the activity of this industry is dumped into landfills, generating an environmental impact that could be reduced by using this waste as a binder in building materials. In the present work, the use of this by-product as an addition for soil improvement of clayey soils has been studied. The tested natural soil is a soft clay from southeastern Spain, which has been mixed by adding 5, 10, 15, 20, and 25% of dry limestone dust by total dry weight of the soil. The natural soil and the additive have been characterized, in addition to the common geotechnical tests, by means of X-Ray diffraction and X-Ray Fluorescence. The improvement of the geotechnical properties of the mixed soil has been evaluated by means of the change in the Atterberg limits, free swell index, unconfined compressive strength, and one-dimensional consolidation test. The change in the microstructure of the mixed soil has been studied by scanning electron microscopy. In general, the results obtained show an increase in the strength of the soil and a reduction of its deformability when limestone powder is added.

“…According to Godenzoni [13], the cementing materials (CMs) are produced by the most conventional stabilizing materials, that is, lime, cement, and their mixes along with other pozzolanic materials. Today, a detailed literature is available, and a worldwide research on expansive soil stabilization using a wide array of classical and emergent materials is still in progress [14][15][16][17][18][19][20][21][22]. Although well-documented studies on the use of numerous stabilizers are available, to these authors', knowledge, no study made between 1990 and 2019 that explains the main and interaction effects of CSMs on the expansive soils, has been found.…”

Calcium-based stabilizer materials (CSMs) exhibit pozzolanic properties which improve the properties of clayey soils by hydration, cation exchange, flocculation, pozzolanic reaction, and carbonation. In this comprehensive review, comprising over past three decades from 1990 to 2019, a mechanistic literature of expansive soil stabilization by incorporating CSMs is presented by reviewing 183 published research articles. The advantages and disadvantages of CSMs as the ground stabilizing agent are succinctly presented, and the major outcomes of physicochemical effects on soil properties are discussed in detail. After blending with CSM, the main and interaction effects on soil properties with focus on chemical processes such as X-ray fluorescence, X-ray diffraction analyses, and microstructure interaction by using scanning electron microscopy and thermogravimetric analysis have been reviewed in light of findings of past researchers. This work will help geotechnical engineers to opt for suitable CSM in the field of geoenvironmental engineering in committing to sustainable construction of civil engineering structures over expansive soils.

Development of Subgrade Stabilization and Slab Undersealing Solutions for PCC Pavements Restoration and Repairs

The loss of functionality and the development of distress in concrete pavements is often attributable to the poor subbase and subgrade conditions and/or loss of support due to the development of the voids underneath the slab. Subgrade soil stabilization can be used as an effective approach to restore the functionality of the subgrades in patching projects. This research had two main objectives: (1) identifying the best practices for soil stabilization of the existing subgrade during pavement patching operations and (2) identifying and developing new, modified grouting materials for slab stabilization and undersealing. Various stabilization scenarios were tested and showed improved performance of the subgrade layer. The use of geotextile along with aggregate course was found to significantly reduce the settlement. Non-removable flowable fill was also found to significantly reduce the subgrade settlement. Cement-treated aggregate and lean concrete provided the best performance, as they prevented formation of any noticeable settlement in the underlying subgrade.
