Abstract :

Owing to the growing demand for power and increasing industrialization huge quantity of fly ash produced every year. It is expected that very soon production of fly ash in India will reach 400 MT per annum. Presently in Portland Pozzolana Cement (PPC) fly ash is a significant constituent however much scope is still available for utilization of fly ash. The present study was intended to explore the possibility of utilization of fly ash in concrete using Portland pozzolana cement (PPC). Portland pozzolana cement was replaced by fly ash in the range of 30 to 60% at an interval of 10% with 10% (by weight of cement) additional lime content. M25 (at 0.45 water/cement ratio) concrete specimens at different replacement levels of PPC were cast and tested for workability at the fresh stage and for compressive strength after 7- and 28-days curing. The result showed that PPC can be replaced up to 30% by fly ash without considerable change in compressive strength.
