“…Several researchers have studied the bearing capacity of the coastal soil deposits [1,2] along with the several performed numerical study [3,4]. Further, several researchers have studied the bearing capacity of the modified ground [5,6]. The study on the modified coastal soil in Kingdom of Saudi Arabia has also been performed by several researchers [7,8].…”

Construction of the foundation on the marine the soil deposit is susceptible to excessive settlement and the construction of foundation is difficult. Although, the most common practice is to construct the raft foundation in these regions even for the low-rise building, excessive settlement can be observed in several building. So, in the present study, laboratory investigations have been done on the marine soil by modifying it with two different type of biopolymer such as Guar gum and Xanthan gum. The geotechnical properties of the soil modified with 1% and 1.5% biopolymer has been evaluated and the obtained properties has been used for settlement analysis. During the settlement analysis, the foundation soil model has been created as layered soil because the top layer has been replaced by biomodified soil. Several combi-nations have been created by varying the thickness of modified soil layer and the type and percentage of modifying agent. The settlement analysis has been performed in the settle 3D software and the biopolymer modification of soil has been found effective in controlling the foundation settlement.

The study focused on the creative development of aggregate column materials and technologies. The seawater (SW) and alkaline agents (AA) were invited to create the recyclable particle materials (RPMs) that were used for the construction of the aggregate columns in the marine environment. The building solid waste (BSW) was utilized to produce the fine powder the chemical activity of which was restored with the help of AA and marine processes. The created products in the study were the RPMs that were also cured in the marine environment. The mechanical and chemical properties were investigated with comprehensive approaches including UCT (uniaxial compression tests), EDS (Energy Dispersive Spectrometer), SEM (Scanning Electron Microscopy), and XRD (X-ray Diffraction). The investigation on the mechanical and chemical properties of the RPMs was carried out at three ages inclusive of 8-day, 49-day, and 583-day. The results from UCTs reported that the UCS (uniaxial compression strength) of RPMs reached 7.29 MPa at 583-day age even in the marine environment. EDS analysis detected the predominant element of RPMs and it was guaranteed that Al, Ca, and Si developed continuously with the age accumulation. Based on XRD and SEM exploration, the principal hydration products and compounds of RPMs used in the aggregate columns included C-S-H, C-A-H, C-A-S-H, N-A-S-H, and CaCO3. Particularly, the salt complexes generated in RPMs filled compactly the microscopic pores of RPMs, which resulted in its densified framework.
