Abstract:

Bottom Ash produced by coal-fired boilers can be used in variety of construction and manufacturing applications which include structural and engineering fill, cement raw material, aggregates for concrete and asphalt products and general reclamation purposes. Physically, bottom ash is typically grey to black in color, is quite angular, and has a porous surface structure. Over a decade ago, removal of bottom ash in dry state was considered impractical. With the increased use of bottom ash, there is a greater interest in applying this in construction practices. This paper presents the experimental investigations carried out to study the effect of use of bottom ash (the coarser material, which falls into furnace bottom in modern large thermal power plants and constitute about 20% of total ash content of the coal fed in the boilers) as a replacement of fine aggregates. The various strength properties of concrete such as the compressive strength, flexural strength and splitting tensile strength are studied. The strength development for various percentages (0-50%) replacement of fine aggregates with bottom ash are carried out which can easily be equated to the strength development of normal concrete at various ages.
