“…These characteristics render them to consider as viable alternatives to traditional cement 25 , 26 . In recent years, chemical grouting materials such as polyurethane and silica sol 27 , butyl acrylate and styrene 28 , sodium silicate 29 , and polyacrylamide 30 have been utilized in soil remediation.…”

The dissolution of soluble rocks (gypsum/anhydrite) beneath the Mosul Dam by water seepage has been observed upon the initial impoundment; consequently, several sinkholes have been manifested in the vicinity of the dam site. Traditional grouting has been envisaged as a potential remedy; however this measure has not eradicated the problem. The main purpose of this study is to overcome the solubility of the gypsum/anhydrite rocks using chemical grouts. Rock samples were acquired from the Fatha Formation outcrop and problematic layers of brecciated gypsum situated at varying depths beneath the Mosul Dam. Two commercially available liquid polymers, polyurethane (PU) and a mixture of acrylic and cement (ARC) were used to investigate their sealing performance in halting of the solubility of the rocks (gypsum/anhydrite). To simulate the dissolution phenomenon under the influence of artificial hydraulic pressure of the dam and the water flow in its abutments, two distinct laboratory models were devised. The outcomes from the experimental study on both untreated and treated samples revealed that the acrylic-cement composite (ARC) and polyurethane (PU) are influential polymers in halting the solubility of the gypsum rock samples under both factors of water pressure and high-velocity water flow.

“…Numerous researchers have recently demonstrated that using solid wastes in geotechnical engineering, especially in stabilized and reinforced soils (SRS), is a suitable solid waste management method. SRS results have been reported by adding various types of additives, including chemicals [11][12][13][14][15][16], biochemicals [17][18][19], fibers [20][21][22], and solid wastes, to improve their weak engineering properties. Traditional stabilizing agents may have negative impacts on the environment and ecology [23,24]; for example, the production of cement or lime consumes high amounts of energy and can result in carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) emission [25,26].…”

The rapid urbanization, industrialization, and population growth have led to a considerable rise in solid waste production, highlighting the need for efficient solid waste management and recycling methods. To address the challenge of solid waste production, an alternative solution is to repurpose it in geotechnical engineering. This offers promising benefits as solid waste exhibits various mechanisms that can improve soil's hydromechanical and mechanical behaviors. This review aims to comprehensively analyze the effects and potential application of various solid waste types to stabilize and reinforce soil. The impacts and research trends of industrial waste, such as fly ash, red mud, ground granulated blast-furnace slag, and construction and demolition waste, as well as agricultural and municipal solid wastes, including rice husk ash, press mud, used waste tires, and face masks, on soil properties were identified. The findings contribute to a better understanding of the potential of solid waste as a sustainable and cost-effective solution for improving soil quality, highlighting new research themes in this area. A wide range of innovative methods to stabilize and reinforce soil have also been proposed; however, ingenious and effective containment techniques, as well as addressing the potential impacts of climate change on stabilized and reinforced soils (SRS), still need to be developed for robust field applications. This state-of-the-art review offers useful insights into the reutilization of solid wastes as a promising alternative for improving the hydromechanical and mechanical behaviors of SRS.

“…In recent years, due to such characteristics as high permeability and strong cementing power, chemical grouting materials, such as sodium silicate [15], polyurethane [10], butyl acrylate and styrene [16], silica sol [10], lignin sulfonate [17], and polyacrylamide [18,19], have been applied through permeation grouting in the impermeable reinforcement of the sand. At the same time, electroosmosis [20] and microbial grouting [21] have also gradually become emerging soil reinforcement techniques.…”

“…e chemical grouting materials generally cement the soil particles via electrostatic and chemical bonding. Meanwhile, they fill the pores of the cluster structure of soil particles [16] and form a thin-film-like structure around the cluster body, thereby improving the stability and strength of the soil body or isolating the contact between soil particles and water to enhance hydrolysis resistance [22]. Despite many achievements about the changes in mechanical properties of special soil bodies such as sandy soils or expansive soils, collapsible soils, and marine clays before and after grouting, the laws of diffusion and performance changes of grout in silt under the influence of grouting pressure have been less studied.…”

To meet the demand of antiseepage and reinforcement of soil dams, a kind of permeable polyurethane grouting material was developed. A visual steady-pressure grouting test device was designed to study the law of polyurethane diffusion and reinforcement in silt under different pressure, and the interaction mechanism of grout and soil body structure was explored microscopically. The results showed that, with the increase in the grouting pressure, the diffusion speed rose, and the diffusion pattern of grout in the soil also changed from permeation diffusion to permeation splitting. Under the effect of grouting pressure, more tiny cracks will occur in the soil structure, leading to the use of more grout, thus increasing the strength of the consolidated soil by more than 10 times. The results of SEM-EDS and mercury intrusion test proved that the polyurethane had a significant filling effect on the soil structure, which could effectively reduce the porosity of the soil and cement the soil particles through wrapping, complexing, and hydrogen bonding, thereby improving the soil properties. Moreover, the results revealed from a microscopic perspective that the grouting altered the pore structure of the soil structure through the seepage-erosion-splitting coupling effect, but when the grouting pressure exceeded 0.4 MPa, the soil particle and grout would be partially remixed and arranged closely, showing a phenomenon of jet grouting. Finally, the material was used in engineering practice, achieving a satisfactory grouting treatment effect.
