“…Cement stabilisation is one among the frequently used methods. Numerous studies have been conducted on the strength and stiffness properties of marine clay treated with high cement content (>10%) (Panda and Rao 1998;Yu et al 1997;Miura, Horpibulsuk, and Nagaraj 2001;Lorenzo and Bergado 2004;Lorenzo and Bergado 2006;Consoli et al 2011;Horpibulsk et al 2011;Yoon, Kim, and Jeon 2011;Dingwen et al 2013;Xiao, Lee, and Chin 2014;Zhang et al 2014). In general, it can be concluded that the primary and secondary cementitious materials formed during stabilization will increase the mechanical strength of the marine clay (Kamruzzaman, Chew, and Lee 2009).…”

The present paper discusses the stress-strain behaviour and critical state parameters of dredged Chennai marine clay stabilized with low cement content (2.5-10%). Series of one dimensional consolidation test and consolidated undrained triaxial tests are performed on the cement stabilized dredged Chennai marine clay to evaluate the critical state parameters (λ, κ, M, Г, N) for varying cement contents and curing days. The results show that the slope of the critical state line Downloaded by [New York University] at 05:38 14 July 20152 M increases with an increase in cement content. The parameter λ for treated marine clay increases up to a cement content of 7.5% followed by a reduction. The parameter κ decreases with the addition of cement content. Finally empirical formulations are proposed to predict the critical state parameters as the functions of cement contents and curing days.

“…Plastic concrete consists of the same materials as those of normal concrete with a high water-cement ratio and the only difference is that clay or bentonite is added to the mixture to increase its ductility (Gao et al, 2009c). This concrete shows great promise to satisfy the requirements of the strength, stiffness and permeability for remedial cut-off wall construction (Yu et al, 1997).…”

Plastic concrete consists of aggregates, cement, water and bentonite, mixed at a high water cement ratio, to produce a ductile material. It is used for creating an impermeable barrier (cut-off wall) for containment of contaminated sites or seepage control in highly permeable dam foundations. The effects of water to binder ratio and clay dosage on mechanical properties of plastic concrete were investigated. The results indicate that the water to binder ratio and clay dosage have great influence on the mechanical properties of plastic concrete. There is a tendency of decrease in the compressive strength, splitting tensile strength, shear strength and elastic modulus of plastic concrete with the increase of water to binder ratio and clay dosage, while, the internal friction angle of the shear specimens is increasing gradually. To improve the resistance to deformation of cut-off walls constructed with plastic concrete, the higher water to binder ratio and clay dosage can be selected to decrease the elastic modulus of plastic concrete in the practical design and applications of plastic concrete on condition that the plastic concrete has enough compressive strength, tensile strength and shear strength.

“…Ensuring compatibility of strain between adjacent soil and the wall helps mitigate the risk of wall over-stressing and allows for deformation without separation 8 . This type of concrete holds significant potential in meeting the criteria for strength, stiffness, and permeability in the construction of remedial cut-off walls 7 . Although it offers enhanced formability, its strength is comparatively lower due to the incorporation of clay slurry 9 .…”

Bentonite plastic concrete (BPC) demonstrated promising potential for remedial cut-off wall construction to mitigate dam seepage, as it fulfills essential criteria for strength, stiffness, and permeability. High workability and consistency are essential attributes for BPC because it is poured into trenches using a tremie pipe, emphasizing the importance of accurately predicting the slump of BPC. In addition, prediction models offer valuable tools to estimate various strength parameters, enabling adjustments to BPC mixing designs to optimize project construction, leading to cost and time savings. Therefore, this study explores the multi-expression programming (MEP) technique to predict the key characteristics of BPC, such as slump, compressive strength (fc), and elastic modulus (Ec). In the present study, 158, 169, and 111 data points were collected from the experimental studies for the slump, fc, and Ec, respectively. The dataset was divided into three sets: 70% for training, 15% for testing, and another 15% for model validation. The MEP models exhibited excellent accuracy with a correlation coefficient (R) of 0.9999 for slump, 0.9831 for fc, and 0.9300 for Ec. Furthermore, the comparative analysis between MEP models and conventional linear and non-linear regression models revealed remarkable precision in the predictions of the proposed MEP models, surpassing the accuracy of traditional regression methods. SHapley Additive exPlanation analysis indicated that water, cement, and bentonite exert significant influence on slump, with water having the greatest impact on compressive strength, while curing time and cement exhibit a higher influence on elastic modulus. In summary, the application of machine learning algorithms offers the capability to deliver prompt and precise early estimates of BPC properties, thus optimizing the efficiency of construction and design processes.
