Influence of Lime and Brick Dust on Compaction and Strength Properties of Clay Soil When Mixed With Ldpe

Soil is an essential part of construction and forms a base for all the essential activities of construction. Soil is not same at all places and sometimes lacks in various properties. So, to improve its various qualities and to meet the engineering requirements like quality, durability, etc., we can achieve it by adding suitable admixtures such as, lime, cement, fly ash, plastic, gypsum etc. This not only improves the properties of soil but also reduces the quantities of waste in the environment. The aim of this study is to experimentally investigate the effects of adding Lime, Brick dust and Plastic and low density polyethylene to Clayey Soil. The low density polyethylene is a vital environmental pollutant and its biodegradation is the focus of the present study. The clay soil used was taken near Baddi, Himachal Pradesh. The optimum contents of Lime, Brick dust and LDPE in the Clay soil was found by Standard Proctor Test and CBR test, and the results showed by adding 20% lime , 8% Brick dust and 1.5% LDPE in the Clay soil, we get the maximum Bearing Capacity of the mixture.

Poor Soil

The poor soil properties result in foundation failures of the structure which further causes in cracks of structural elements and walls. To avoid this, it is essential to enhance the soil properties. Soil stabilization is one of the processes to improve the engineering properties of the soil and thus making it more stable. It is required when the soil available for construction is not appropriate for the intended purpose. In this research, for stabilizing clayey soil and to achieve higher strength in minimum time period, gypsum (CaSO4.2H2O) is used as one of the soil stabilizing agents. Experiments were planned to evaluate the properties of clayey soil on the addition of different percentages of Gypsum i.e., 2%, 4%, 6% and 8% to the existing soil. Tests conducted on clayey soil mixed with Gypsum included are, Atterberg’s Limits, Specific Gravity and Standard Proctor Test. A comparison between the properties of clayey soil, clayey soil mixed with Gypsum is done to understand the effect of Gypsum addition on soil properties. It was observed that the soil properties were enhanced for 6% of Gypsum addition to the soil.

The development of population, quick urbanization and more development of structures and buildings has brought about the decrease of good quality land. To improve the accessibility of good quality land, strength and compaction properties of land should be improved. The fundamental goal of this examination is to explore the utilization of fly ash, lime sludge and polypropylene fiber in Geotech highway application and to assess their impact on quality and compaction of soil, utilized for subgrade. The soil samples were gathered from the zones of Chandigarh where clayey soil is present in abundance. The laboratory testing led to decide the strength and compactive effort of the clay soil. This investigation includes three principle tests. The primary test is standard proctor test. The subsequent test is California bearing ratio and the third test is the direct shear test. Proctor test gives the compactive effort of the soil and CBR gives the subgrade strength. The outcomes acquired are thought about for the examples and inferences are drawn towards the unstability and effectiveness of admixture support at different percentages, as replacement for high quality subgrade and cost-effective approach.

Abstract: Generally clay exhibits undesirable engineering properties like poor bearing capacity and higher compressibility. Thus the improvement of the soil at site is indispensable. There are many stabilizers to improve the strength of soil like Jute, Gypsum, fly ash, rice husk ash, cement, lime used rubber tyres etc. In the present Study , we added jute and gypsum as stabilizer to improve the properties of clayey soil . Locally available clayey soil is used in this study . The objective of this study is to improve the strength of the clayey soil by making soil-jute and soil-jute-gypsum mixture. six specimens are prepared to investigate the properties of soil out of which three specimens are prepared by adding 1% of jute with varying length of 1cm,2cm and 3cm and the remaining three specimens are prepared by adding 1% jute and gypsum each with varying length of 1cm,2cm and 3cm of jute . Standard proctor test and unconfined compressive strength test are conducted to analyse the optimum moisture content (OMC), Maximum dry density (MDD) and compressive strength of soil mixture.

Present study deals with the correlation between structural and mechanical characterization of sub-grade soils to increase the strength of soil for road. Clays are generally poor materials for foundations due to large lateral pressure and low resilient modulus. This investigation were carried out with waste products(Agricultural waste) like Rice Husk Ash (RHA) along with various percentages of locally available lime. X-ray fluorescence (XRF), California Bearing Ratio test (C.B.R), Standard Proctor Test, Unconfined Compression Test were done on these samples to characterize the structural and mechanical properties as significant increase in strength properties were observed in the soil samples upon mixing with RHA and lime. It was observed that soaking strength is around 16.8 for the Sample C-3 (Soil+9% RHA). Increase of strength may be due to the reduction of mica in the soil sample. Increase of the silica in the soil sample finally increase the strength and stability. The maximum soaking strength was observed 24.82 for the Sample C-7 ( Soil + 9 % RHA + 8 % Lime). It is obvious because the wt.% mica phase become minimum for this composition. XRF results also reveals that silica and calcium contents are maximum for this composition. So microstructural results revealed that the mica phase may play very important role for maintaining the strength and stability of the soil.
