“…In civil engineering, the enhancement of soil properties is a common practice that aims to provide the soil with the required properties to support the infrastructures, by using techniques that result in improving soil resistance and reducing compressibility or permeability, among other aspects. Several techniques for soil improvement have already been developed and applied in the field of geotechnics, being classified as mechanical, chemical, biological, thermal and hydraulic (Khajeh et al , 2020; Esfandiari and Jamshidi, 2014).…”

“…One of the most common and widespread techniques for soil improvement is the solidification/stabilization by the addition of Portland cement, used as an agent of solidification and stabilization to the soil, providing geomechanical improvements (Khajeh et al , 2020) or, in addition, remediation of contaminated sites (Xia et al , 2018), depending on the case. Besides the Portland cement, other stabilizing agents, such as zeolite, fly ash, silica and metakaolin (Khajeh et al , 2020; Jadhav et al , 2018; MolaAbasi et al , 2019; Ng, 2018), have been applied to achieve these goals. At the same time, fiber elements, such as glass fiber, nylon fibers and polyester fibers, could also be added to reinforce the soil (Khajeh et al , 2020; Festugato et al , 2018; Consoli et al , 2019; Estabragh et al , 2011; Vinoth et al , 2018).…”

“…Clay soils can be solidified and stabilized by cement-based composites, nylon fiber-based composites, hydrothermal and even waste materials as discarded glass and blast furnace slag (Estabragh et al , 2011; Inazumi et al , 2020; Zhou et al , 2012; Du et al , 2019). In its turn, silica-sand soil could be enhanced by classical techniques such as cement-based composites or by other methodologies such as fiber-composites, low-carbon and rapid-hardening cements, sustainable binders and more eco-friendly compounds (Khajeh et al , 2020; Ng, 2018; Consoli et al , 2019; Vinoth et al , 2018; Li et al , 2017).…”

Purpose The purpose of this article is to analyze the state-of-the art in a systematic way, identifying the main research groups and their related topics. The types of studies found are fundamental for understanding the application of artificial neural networks (ANNs) in cemented soils and the potential for using the technique, as well as the feasibility of extrapolation to new geotechnical or civil and environmental engineering segments. Design/methodology/approach This work is characterized as being bibliometric and systematic research of an exploratory perspective of state-of-the-art. It also persuades the qualitative and quantitative data analysis of cemented soil improvement, biocemented or microbially induced calcite precipitation (MICP) soil improvement by prediction/modeling by ANN. This study sought to compile and study the state of the art of the topic which possibilities to have a critical view about the theme. To do so, two main databases were analyzed: Scopus and Web of Science. Systematic review techniques, as well as bibliometric indicators, were implemented. Findings This paper connected the network between the achievements of the researches and illustrated the main application of ANNs in soil improvement prediction, specifically on cemented-based soils and biocemented soils (e.g. MICP technique). Also, as a bibliometric and systematic review, this work could achieve the key points in the absence of researches involving soil-ANN, and it provided the understanding of the lack of exploratory studies to be approached in the near future. Research limitations/implications Because of the research topic the article suggested other applications of ANNs in geotechnical engineering, such as other tests not related to geomechanical resistance such as unconfined compression test test and triaxial test. Practical implications This article systematically and critically presents some interesting points in the direction of future research, such as the non-approach to the use of ANNs in biocementation processes, such as MICP. Social implications Regarding the social environment, the paper brings approaches on methods that somehow mitigate the computational use, or elements necessary for geotechnical improvement of the soil, thereby optimizing the same consequently. Originality/value Neural networks have been studied for a long time in engineering, but the current computational power has increased the implementation for several engineering applications. Besides that, soil cementation is a widespread technique and its prediction modes often require high computational strength, such parameters can be mitigated with the use of ANNs, because artificial intelligence seeks learning from the implementation of the data set, reducing computational cost and increasing accuracy.

“…Also, the work is stretched to understand the factors affecting the strength of stabilized soil such as organic matter, sulphates, sulphides, compaction, moisture content, temperature, and freeze-thaw and dry-wet effects. Khajeh et al, [20] they have studied the fundamental soil-cement stabilization practice. Four types of cemented soil study are carried out; they are cement-stabilized clays, cement-stabilized sands, cemented soils, and reinforced cemented composites.…”

Expansive soils are the soils that expand when comes in contact with water and shrinks when the water within them gets evaporates. These soil are treated as problematic soils for various construction activities hence there is an essential to improve its strength against load effects and also to alter their behaviour against moisture conditions. This review aimed to study the behaviour of expansive soil stabilized using various natural and industrial processed materials such as cement, polymer, lime, rice husk ash, stone dust, fly ash, coir fiber and its pith, jute, bagasse ash and ground granulated blast furnace slag (GGBS). The paper covers the discussion on experimental test results of black cotton soil conducted by various researchers. The tests being basic geotechnical properties, maximum dry density and optimum moisture content, unconfined compressive strength test (UCS), California bearing ratio (CBR), etc., are presented.
