Physical and Mechanical Properties of Fly Ash of Kosova B TPP for Utilization as Product for Partial Cement
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
In Kosovo the electricity generation from lignite-fired power plants produces around 1 Mt/annually of fly ash as combustion byproduct. The energy demand in Kosovo increases each year and the same with the lignite consumption that directly leads to the increase of fly ash production. Since the first operation of first thermal power plant till now there are around 27 Mt of unutilized fly ash, i.e. fly ash in Kosovo has not been treated or utilized at all. In the other hand, the concrete industry, respectively cement production process is associated with CO2 emission, around 5% of world’s CO2,which is a greenhouse gas. The cement production is increasing due to high market needs and consequently more CO2 emission in the atmosphere. The results of studies and researches show that each tonne of cement contributes with the emission of around 1 tonnne of CO2. In this paper, the studying of physical and mechanical properties of Kosovo B TPP Fly ash intends to boost efforts for utilization of fly ash of Kosovo as partial cement replacement or admixture through its standardization as construction product. The benefits of this utilization will be of great importance for saving the environment, the improvements of many properties of concrete built with a certain percentage of fly ash, and finally with the direct substitution of cement with fly ash which results with the decrease of CO2 emissions from cement industry. The test results of this study are in favor of these benefits.
