Effects of Steel Slag on the Strength Properties of Clay, Lateritic and Black Cotton Clay Soil

Excessive use of materials, leads to industrialization, which has an adverse impact on the environment. From industries, large amount of chemicals or other suspended particles as a waste are produced, which are mostly dumped that acquires large space leading to deterioration of soil properties. So, we should use these waste for some constructive or useful purposes. As steel industry releases waste with some good engineering properties so, we can use this type of waste with soil which has low strength and does not have good engineering properties. Various techniques are available like soil stabilization, providing reinforcement etc. to improve load bearing capacity of soil. Soil stabilization is one of the modification techniques used to improve the geotechnical properties of soil and has become the major practice in construction engineering which enables the effective utilization of industrial wastes as a stabilizer. This technique becomes more popular because of its easy availability and adaptability. In this study, the steel slag (an industrial waste) is mixed with Clay(CI), Lateritic(A-7-6(5)) , Black cotton clay soil to enhance its strength properties and make them more suitable for use. In this way industrial waste can be reduced economically.

Strength Characterization of Cement Stabilized and Fiber Reinforced Clay–Pond Ash Mixes

This paper presents the experimental results obtained from tests conducted on clayey soil specimen stabilized with pond ash (PA) and cement and reinforced with randomly distributed fibers. The amount of PA and cement were varied from 0–50 and 0–6 % respectively by dry weight of the soil. In order to understand the influence of admixture on the strength properties of clay, compaction tests, unconfined compression tests (UCS), split tensile strength (STS) tests and California bearing ratio tests (CBR) were conducted. In addition scanning electron microscopy and X-ray diffraction tests were carried out on certain samples in order to study the surface morphological characteristics and hydraulic compounds, which were formed. The specimens were tested for their strength behaviour at different curing periods. The obtained results have shown that addition of mixtures leads to a decrease in the maximum dry density and increase in optimum moisture content. The results also indicate that the proposed method is very effective to improve the strength of the clayey soil in terms of UCS, STS and CBR tests.

Stabilization of Clay with Using Waste Beverage Can

This work presents an investigation of the effect of waste aluminum beverage cans strips on strength and swelling properties of lean clay. Waste beverage cans (WBC) were cut into 5mm strips and mixed with soil in 2, 4, 6, 8, and 10% (dry weight of soil) before use. Three standard tests were carried on the prepared samples: compaction, free swelling, and California Bering Ratio (CBR). Test results showed that WBC significantly affected the compaction characteristics, swelling and strength properties of the clay.

Comparison of True and Residual Friction Angles

ABSTRACT Both original and shear-induced fabrics have a significant influence on the deformation and strength properties of clays. The shear-induced structure appears to be the prime cause for the formation of constant residual angle irrespective of the stress history or the initial structure. Initiation of shear-induced fabric is controlled by the mobilization of true angle of friction. A comparison of true and residual friction angles from field data is made. The correlations of Bjerrum for residual friction angle and Skempton-Gibson- Bjerrum for true friction angle with plasticity index have been used to get additional data for the comparison. It is found that the residual friction angle is nearly equal to true friction angle for soils with clay content greater than about 40%. Residual friction angle approaches true friction angle at low normal pressure in soils with high percent of montmonillonite.
