Way of reduce the pollution of pond ash disposal determinations is recycled and reuse in different engineering applications. The quality of pond ash can affect the quality and strength engineering applications. In this research paper to achieve strength pond ash is replaced by sand at different proportion as 7.5%, 15%, 22.5%, 30%, 40% and 50%. For these proportion some laboratory tests as compaction test, CBR tests, and direct shear tests are conducted. As per results found that addition of sand by replacing pond ash have better outcomes. Key Words: Pond ash, Sand, Angle Of internal friction, Shear Strength, CBR 1. INTRODUCTION Pond is a waste material obtained from burning of coal. The main aim of this research is to utilization of pond ash and the minimize the effect on the environment on an account of dumping of huge amount. The disposal of pond ash can pollute the water resources including ground water. There may be air pollution from small dust particle of pond ash when pond ash deposits in dry condition without water. By this process of utilization the construction of embankments, roadways, and many more can become economical. For achieve the strength of pond ash which is replaced by sand. To satisfy this objective, an experimental work was done to investigate the impact replacing sand at several proportion 7.5%, 15%, 22.5 %, 30%, and 40% and 50% insertion on the geotechnical behaviour of pond ash. In this study section 2 describes literature views of past studies, section 3 having properties of materials used in this research. Section 4 presents experimental investigation used for this study and section 5 presents experimental outcomes. Finally section 6 offerings conclusion. 2. LITRATURE REVIEWS Prabhakar and Sridhar (2002) 1 In this research randomly oriented sisal fiber as reinforcement c- Ф soil at four different percentage 0.25, 0.5, 0.75 and 1% by weight of raw soil and four different length of fiber 10,15,20 and 25 mm is used and found momentous improvement in shear strength parameters of the soil. Rakesh Kumar, Vijay Kumar Kanuajia (1999) 2 this study conducted on the silty sand and pond ash specimens reinforced with different polyester fibers. According research data the inclusion of fibers in sand increases CBR value, friction angle. Shilpi Gupta, Prateek Negi, Ashok Gupta (2003) 3 - This research paper based on the study of the effect of the lime and pond ash on geotechnical parameters of sand. Fine sand is used in this study, in presence of moisture, pond ash with lime is making a cementation components which helps to improve the strength of weak soil. A series of experiments including x – ray diffraction is performed for this study for direct proportion of sand with pond ash and lime. This research indicates the MDD of sand is increased with the percentage of lime and MDD increases with up to 8% pond ash after that it decrease. CBR value also increases with the percentage of pond ash and lime and angle of friction also increases up to 9% pond ash and after that it decreases. Ratna Prasad, Darga Kumar , N. (2015) 4 - In this Research on the stability of fly ash at 25% fly ash shows that the effect is better in terms of CBR and strength. As the percentage of fly ash increases from 0% to 25%, the CBR value under both unsoaked and soaked conditions will decrease. For fly ash content exceeding 15%, the CBR value will decrease by about 50% to 65% under both non-wetting and wetting conditions. The percentage of fly ash increases from 0% to 25%, and the internal friction angle of gravel soil decreases. This reduction in the angle of internal friction hardly exceeds 10% of fly ash. From 15% to 25% of fly ash, the observed internal friction angle is almost constant, with a value between 360 and 380. The fly ash in the sidewalk and the base material can effectively use up to 25% of the fly ash construction 3. MATERIAL USED 3.1 Pond Ash The pond ash produced from Kota super thermal power station, the material was by product from coal combustion collected from power plant dumping area. Index properties of pond ash are following in Table 1.
