Currently India produces around 120 million tones of fly ash per annum. The power requirements of the country have increased a lot due to industrial growth. India mainly depends on thermal power which contributes about 80% of the power produced resulting in accumulation of huge quantity of fly ash as residue. It is estimated that ash generation is likely to reach 170 million MT by 2010; only 32 % of the fly ash is utilised which needs an urgent attention. Effective utilizing of high and low volume of fly ash in concrete (HVFAC&LVFAC) has positive effects in an environmental friendly way, preserving resources and producing better concrete. This paper presents the experimental investigation carried on HVFA and LVFAC in concrete and the environmental benefits rendered by it.

Abstract


Currently India produces around 120 million tones of fly ash per annum. The power requirements of the country have increased a lot due to industrial growth. India mainly depends on thermal power which contributes about 80% of the power produced resulting in accumulation of huge quantity of fly ash as residue. It is estimated that ash generation is likely to reach 170 million MT by 2010; only 32 % of the fly ash is utilised which needs an urgent attention. Effective utilizing of high and low volume of fly ash in concrete (HVFAC&LVFAC) has positive effects in an environmental friendly way, preserving resources and producing better concrete. This paper presents the experimental investigation carried on HVFA and LVFAC in concrete and the environmental benefits rendered by it.
