... Abstract Electrochemical stabilization is a promising technique to improve the engineering properties of weak soils by injecting chemical cementation agent(s) into the soil matrix during the electrokinetic process. The predominant mechanism of electrochemical stabilization is the combination...

... This study evaluates the constrained modulus (M) and the small strain shear modulus (G max ) of cemented sand from cone tip resistance (qc). For this, a series of piezocone and bender element tests are performed in a large calibration chamber, and one-dimensional compression tests are also...

... A large scale experimental study was conducted on electrokinetic cementation of calcareous sand for offshore foundations. A steel tube, 200 mm in diameter and 400 mm in length was used as a model caisson. Calcareous sand and seawater from the coastline of Western Australia were used in the study...

... ABSTRACT The effect of the electric field intensity on electro-cementation of calcareous sand was studied via the large model tests and the electric field analyses. In the experiments, the model caissons were embedded in calcareous sand and a dc intermittent electric field was applied via...

... ABSTRACT A laboratory floor experimental study was conducted on the electrochemical cementation of calcareous sand for offshore foundations. A caisson, 200 mm in diameter and 400 mm long, was embedded in a calcareous sand under seawater. The calcareous sand and seawater used in the study were...

... ABSTRACT The behavior for the artificially cemented granular soils is investigated in this paper. Blast furnace slag cement is used in the test and compared with ordinary Portland cement. As the cement content increases, both peak strength and initial stiffness increase. Besides, cemented...

... behavioral responses of calcareous sediments. Natural cementation between particles further complicates the behavioral properties of this soil type. Triaxial cyclic strength testing of calcareous and silica sands was performed in conjunction with full-scale cone penetration tests performed in a calibration...

... A series of isotropica1ly consolidated undrained triaxial tests have been performed to under stand the response of an artificially cemented marine clay under static compression loading. The investigation highlights the role played by cementation on the stress-strain curve, failure strain...

... Abstract: This paper presents laboratory studies of K. of two artificially cemented sands. A modified odometer ring capable of measuring lateral earth pressure at-rest was used for the tests. Test specimens were prepared using 0, 0.5, I, 2, 4 and 8% of portland cement. It IS found that K...

... ABSTRACT: This study shows that calcium carbonate plays an important role as cementing agent of Tokyo bay sediments, as found in other bay sediments. The measured vane shear strength and unconfined compressive strength of the sediments are shown to vary with depth and are strongly dependent...
