Impact Of Curing Temperature On The Strength Of Lime Preserve Fly Ash

Fly Ash in India is about 112 million tones with 65000 acre of land being occupied.In recent times the usage of fly ash as one of the dominant construction material. To enhance and improve the properties of fly-ash by stabilizing with lime. In this work aimedto evaluation of the impact of lime as stabilizing material to the fly ash. The geo-engineering properties of fly ash alongfly ash with different proportion of lime were conducted. Following tests light and heavy compaction test, unconfined compressive strength test, permeability test and CBR tests were studied for fly-ash sample. The stabilized fly-ash was done by adding lime with varying (2%, 4%, 8% & 10%) percentages. The UCS samples were cured for 7, 14, and 28 Days with different temperatures of 10o, 27o, and 50o. The potential and efficiency of adding disposed fly ash from Mae Moh Electric Power Plant, Thailand, into cement-admixed clay were studied by means of a series of UC and physical tests (Jongpradist et al. 2010). An experimental study was conducted to investigate the long-term performance of fly ash stabilized two fine-grained soil sub-bases (Shafique et al. 2009). A number of researches on study of using fly ash in the field of geotechnical engineering has been reported, such as the preserve of soil in compaction works of highway embankment or slope without cement or lime (Edil et al.2006; Kim et al. 2005; Prabakar et al. 2004) with cement (Kaniraj and Havanagi 1999) and with cement and fiber reinforcement (Kaniraj and Havanagi 2001). Numerous studies on application of fly ash as bulk fill material are also available (Raymond 1958; DiGioia and Nuzzo 1972; Gray and Lin 1972; Joshi et al. 1975) which demonstrated the possibility of utilizing huge amount of fly ash in the construction of embankments, dykes, and road subgrades. A wide range of soils can be stabilized using fly ash (Chu et al. 1955; Geocker et al. 1956; Viskochil et al. 1957; Ghosh et al. 1973; Vasquez and Alonso 1981; Lo and Wardani 2002). Other uses of fly ash are land reclamation (Kim and Chun 1994), and injection grouting (Joshi et al. 1981). Ghosh et al. (2005) demonstrated the use of fly ash as foundation medium reinforced with jute-geotextiles. Undrained shear strength parameters of fly ash were reported by Raymond (1961)
