Grouting, Rheology, and Soil Mechanics

Polycarboxylate ether (PCE) water-reducing admixtures have emerged as promising solutions to optimize clinker grinding and properties. The increased adsorption ability of PCE and creation of narrow particles, despite maintaining constant Blaine fineness, has sparked the interest of their use as grinding aids (GAs) in…

Historic masonry structures frequently develop internal voids, cracks and loss of bonding due to ageing, environmental actions and previous incompatible repairs. Grout injection is widely used to restore structural continuity; however, the in-situ performance of commercial hydraulic lime-based grouts remains insuffici…

This study presents an experimental framework to isolate intrinsic biopolymer bonding from strength gains induced by densification in stabilized high-plasticity clay. Xanthan gum (XG) and κ-carrageenan (CG) were evaluated using two preparation methods: Method A, in which biopolymer replaces an equivalent soil mass to…

Industrial wastes used as additives in soils are widely applied due to their low cost and ability to prevent environmental pollution. This study investigates the effect of Glass Fiber Reinforced Polyester (GRP) pipe-cutting waste on the shear strength of fine-grained soils. This effect was evaluated for silty soils in…

Problematic fine-grained soils exhibit low strength and inadequate durability, highlighting the need for sustainable stabilization using eco-friendly binders. This study examined the strength development and durability of a natural CH soil (NSs) stabilized with fly ash (FA) based geopolymer exposed to sulfate attack a…

This study investigates the use of a pumice-based geopolymer as a sustainable stabilizer for expansive clay, with emphasis on strength development, volumetric stability, and stress-dependent cyclic behavior. Although geopolymer binders have been widely explored, pumice-based systems for clay soils remain limited, part…

Sulfate-rich soils (SRS) exhibit poor engineering properties, and studies focusing on the stabilization of these soils remain limited in the existing literature. Previous research has shown that the use of calcium-based stabilization agents, such as cement and lime, during the treatment of SRS can lead to adverse effe…
