The Stability

The purpose of this study is to determine the properties of laterite soil and how they affect the stability of bitumen stabilized bricks. The samples for the study were disturbed samples sourced in seven locations in Adamawa State. Each sample weigh 20kg transported to the laboratory for tests. The tests conducted include: Sieve Analysis, sedimentation Test, Liquid Limit Test, Plastic Limit Test, Activity Ratio, Free Swell Test and Optimum Moisture Content Test. Three research questions guided the study and the findings of the study include; that the samples shows increase percentage smaller or less than 63 microns sizes, which indicate that the samples are more of silt and clay particles. The properties of the laterite soils taken for the study include; liquid limit ranging from 35-49, plasticity index from 11-14 percent, the activity ratio ranges from 1.0-1.4, and free swell test shows less than 100 percent. One of the recommendations made was that, Laterite soil stabilization should precede a study of the particles size distribution to ensure that the categories of the Laterite soil can bland with the bitumen emulsion to envelop the particles for the purpose of preventing moisture movement in the bricks.

The objective of this paper is to determine the optimum fly ash content at which soil behavior is improved. Soil improvement is termed as soil stabilization. Soil stabilization depends on factors such as unconfined compression, cohesion, shear load, consolidation and permeability of soil and CBR value of soil. Fly ash is a thermal waste. Nearly half of the fly ash generated is not been used, hence usage of fly ash will reduce waste. Test conducted were sieve analysis, specific gravity, standard proctor compaction, unconfined compression, direct shear, free swell index, variable head permeability and consolidation for black cotton soil. Test also was conducted on soil replaced with fly ash in the level of 5%, 10% and 15%. Among the various replacement tried out, better results were observed for soil replaced with 10% of fly ash. Beyond the 10% level of replacement a reduction in performance was observed. Hence fly ash can be used for soil stabilization up to 10% replacement.

Waste management is one of the most critical issues in Bangladesh. Every day thousands of people are dumping their daily household wastes in some specific dumping sites. The leachate that is being generated from these wastes is changing the quality of the soil by mixing with the surrounding soil and is also contaminating the groundwater. Several components such as water and different varieties of salt are found in the leachate. This paper represents the findings of a recent study on the effect of inorganic NaCl salt on certain geotechnical properties of clay soil mixed with bentonite used as a liner material. The clay soil was collected from a local household waste dump in the Khanabari area of Khulna district. The soil was mixed with different percentages of bentonite (10% & 20%) to test the effect of various concentrations (0M, 0.1M & 1M) of inorganic salt. For this reason, laboratory tests like compaction test, liquid limit test, 1-D consolidation test, permeability test, free swell test and pH test were performed. Finally, it was concluded that a salty environment could have a significant effect on the mixture's geotechnical characteristics.

All structures built on soft soil may experience uncontrollable settlement and critical bearing capacity. This may not meet the design requirements for the geotechnical engineer. Soil stabilization is the change of these undesirable properties in order to meet the requirements. Traditional methods of stabilizing or through in-situ ground improvement such as compaction or replacement technique is usually costly. Now a safe and economic disposal of industrial wastes and development of economically feasible ground improvement techniques are the important challenges being faced by the engineering community. This work focuses on improving the soft soil brought from Baghdad by utilizing the local waste material for stabilization of soil, such as by using “Nylon carry bag’s by product” with the different percentage and corresponding to 1 %, 3% and 5% (the portion of stabilizer matters to soil net weight) of dried soil. The results indicated that as Nylon’s fiber content increases, the liquid limit decreases while the plastic limit increases, so the plasticity index decreases. Furthermore, the maximum dry density decreases while, the optimum moisture content increases as the Nylon’s fiber percentage increases. The compression index (decreases as the Nylon’s fiber increases and provides a maximum of 43% reduction by adding 5% nylon waste material. In addition, the results indicated that, the undrained shear strength increases as the nylon fiber increases.

Clay is a cohesive and very soft soil if it has high water content. To overcome this problem, clay soils with high plasticity need to be stabilized. The method of soil stabilization with lime is an alternative effort to improve soil that does not meet the standards. Lime reacts with groundwater so that it changes the property of the soil, reducing the stickiness and softness of the soil. Lime also functions to solidify (stabilize) and stabilize (stabilize) soil in the form of fine powder consisting of metals and inorganic mineral composition. This study aims to determine the effect of clay soils when carried out stabilization by using a limestone additive which varies in levels of mixture. The results showed that lime effective for the stabilization high plasticity and expansive clay by increasing the compressive strength value of UCS with lime content of 10% under curing conditions in 28 days and unsoaked by 319%, the liquid limit value reduced by 6% and the plastic limit value increased by 46%.

Many pozzolans are waste products from industrial processes. Every year a huge amount of coal waste is gathered from the coal washing plant in the Hyrcanian forests of Iran. These materials can be used for soil stabilization in construction and maintenance projects of forest roads. This paper aims to (a) investigate the role of coal waste (CW) as a soil stabilizer and (b) determine the changes in soil specification regarding the environmental pollution in different combinations of materials (soil, lime (4 and 6%) and CW (3, 6, 9 and 12%)). For this purpose, different technical and environmental analysis and laboratory tests were performed. Technical tests showed that the soil liquid limit and maximum dry density decreased with an increase in lime and CW contents. Addition of CW could increase the soil CBR, UCS and OMC. According to XRD test, the addition of CW and lime can increase the size of crystals in stabilized soil samples. Environmental analysis showed that the use of stabilizer significantly reduced the concentration of heavy metals such as Cd, Cr and Pb. Also, all of the metal concentrations leached from samples satisfied the required criteria, but the addition of lime and CW increased the concentration of N, P, and K. These changes can increase the invasive species consistent with calcareous soil conditions along the roads. According to the results, the combination of coal waste and lime can be one of the best methods for in situ remediation. It would, however, be better to use a minimum amount of stabilizer in pavement layers of access roads due to environmental sensitivity.

AbstractA useful method for the disposal of waste from an incineration plant is to reuse it for geotechnical and civil engineering applications. The primary objective of this study concerns the reuse of local incinerated ash from municipal solid wastes in soil stabilization. Municipal Solid Waste Incinerated Ash (MSWIA) is blended with soil in various combinations and tested for its Atterberg limits, unconfined compressive strength (UCS), California Bearing Ratio (CBR), and Free Swell Index (FSI). A 1-D Consolidation Test was conducted, and changes in the soil during the test were examined by a scanning electron microscopic (SEM) analysis. The test results showed that there are increments in the UCS and CBR values with the reductions in the FSI, swell pressure, and swell potential of the treated soils.
