This
As a pioneer in the utilization of fly ash for soil stabilization in Oklahoma, Evans & Associates specializes in the marketing and use of Type “C” fly ash for many stabilization applications including paving sub grade, building pads, select soils, soil conditioning, and waste solidification.
The current utilization of fly ash is only about 55%, mainly in the areas of cement as well as concrete manufacturing and building products and to some extent in earth fills. Coal based thermal power plants generate huge amount of fly ash that is a major problem of disposal of fly ash in India .
In this paper, the utilization of fly ash in construction, as a low-cost adsorbent for the removal of organic compounds, flue gas and metals, light weight aggregate, mine back fill, road sub-base, and zeolite synthesis is discussed.
A comparison of fly ash particles sizes to those of several types of soils is presented in the Figure 1.1. Fly ash is a fine residue composed of unburned particles that solidify while suspended in exhaust gases. Fly ash is carried off in stack gases from a boiler unit, and is collected by mechanical methods or electrostatic precipitators
shall endeavor on planning for 100 percent ash utilization from the initial stage of commissioning of the projects. All power plants are expected to have well tied up program of ash utilization by user agencies, dry fly ash collection, and storage and making available dry fly ash to the user agencies outside the plant boundaries

Fly-ash Utilization in Horticulture RESULTS & DISCUSSION The physico-chemical properties of the flyash used in the experiment as shown in Table 1 indicated its significantly alkaline nature (pH 8.8 ±0.4). Higher ionic concentration was evident through the higher electri-cal conductivity, as has also been discussed by Eary et al. (1990). Metal
