Pani, Aparupa (2014) Effect of Curing Temperature on the Strength of Lime Stabilized Fly Ash. MTech thesis.
For popularizing the usage of fly ash as one of the dominant construction material, it is advisable to enhance and improve some properties of it by stabilizing it by addition of some suitable stabilizer like lime. This project work aims at evaluation of the effectiveness of addition of lime as an agent in stabilizing the waste product like fly ash and its suitability to be used as a construction material for structural fills and embankment materials. Fly ash used for experimentation in this project was collected from the thermal power plant of CPP- NSPCL, Rourkela Steel Plant. For evaluating the suitability of any construction material for various geotechnical engineering works its consistency properties, compaction properties, strength parameters and settlement properties are the most important properties to be tested. In this project, an attempt was made to evaluate the above stated geo-engineering properties of fly ash along with the treated fly ash with different proportion of lime. The overall testing program was conducted in two phases. In the first phase, the physical and chemical characteristics of the fly ash samples were studied by conducting Hydrometer analysis, UCS test, Permeability test and CBR test. In the second phase of the test program, fly ash was mixed with 2%, 4%, 8% and 12% of lime. Lime was added as a percentage of dry weight of Fly ash. The particular UCS samples were cured for 7, 15, 30, and 60 days with varying temperature of 10°C, 25°C, 45°C and 90°C respectively to evaluate the effect of curing temperature on strength of lime stabilized flyash.
