The only exception was the deicing salt-scaling test in which the performance of the concretes investigated was less than satisfactory. The beam specimens (100 mm x 100 mm x 500 mm) were cast and tested for determination of flexural strength of concrete at different replacement levels. Historically, fly ash has been used in concrete at levels ranging from 15% to 25% by mass of the cementitious material component.The actual amount used varies widely depending on the application, the properties of the fly ash, specification limits, and the geographic location and climate. So it is very important to dispose these wastes without affecting the environment. PPC Cement: Pozzolana is a natural or artificial material which contains silica in the reactive form. The experiment program included test on workability, slump loss and compressive strength. shrinkage, and strength of the concrete were evaluated. The results showed that the coefficients of permeability and consolidation of the compacted fly ash were comparable to those of nonplastic silts. Portland cement was replaced with three percentages (40%, 45%, and 50%) of Class F fly ash. The addition of lime and silica fume also improved the sorptivity of concrete.Through the use of differential scanning calorimetry and thermogravimetric analysis (DSC/TG), it was demonstrated that the addition of hydrated lime increased the Ca(OH)2 content; whereas the addition of silica fume decreased the Ca(OH)2 content in the cement paste. When Class F fly ash is used as a replacement for cement, the 7-day compressive strength remains at or above 27.6 MPa until the percentage of fly ash is approximately 45%. To this end, this procedure is divided into seven mixed lots. The geotechnical utilization of the Dadri fly ash has been explained through illustrative examples. The use of fly ash in concrete can reduce the consumption of natural resources and also diminishes the effect of pollutant in environment.
