Cemented soil

The present paper also includes strength prediction models that consider the influence of curing temperature. In addition, the Thermogravimetry analysis (TGA) used to determine the chemically bound water content in cement-treated soil and the X-ray diffraction (XRD) test to explain the chemical mechanism in cement-treated soil are also mentioned.

The brittleness index exhibits the strain-softening behaviour of soil and is often used to access the shear mechanism in slope failure. It has been widely investigated for diffirent materials, especially for brittle materials.

Research purposes: To identify the content of fine gravel to improve the density of the soil to meet the standard of upgrading and repairing the earth-dam. To identify the proper content of cement to reduce the disintegration of the soil that contains a significant amount of fine gravel to meet the standard of upgrading and repairing the earth-dam.

From the experimental studies on the indoor model, the analysis of the software model under the load of the column system combined with the high strength geogrid considering the ground pressure, the column deformation, and the mesh deformation, propose new calculation formulas, which are more suitable in GRPS design.

This paper deals with using stainless steel reducing slag (SSRS), a byproduct generated from stainless steel making process, as a cement substitute in production of soil-based controlled low-strength material (CLSM). In the CLSM mixture, surplus soil and river sand were blended well together with a sand-soil proportion of 6:4 by volume in order to produce fine aggregate. Totally, twelve mixtures were prepared for experiment when we changed in turn percentages of Portland cement replacement with SSRS of 0%, 10%, 20%, and 30% by weight and the water-to-binder ratio of 3.4, 3.6, and 3.8.
