density of flyash

Fly Ash Properties

The specific gravity of fly ash usually ranges from 2.1 to 3.0, while its specific surface area (measured by the Blaine air permeability method)may range from 170 to 1000 m2/kg. The color of fly ash can vary from tan to gray to black, depending on the amount of unburned carbon in the ash. The lighter the color, the lower the carbon content.

Differences Between Portland Cement Concrete and Fly Ash ...

Jul 17, 2017· If the concrete contains a high amount of fly ash, the water used to create it will be absorbed more readily and the concrete mixture will become thicker and more resistant to movement. This is a negative attribute if the concrete needs to be carefully molded or sculpted into specific patterns.

4.1.1 Strength Activity Index— The test for strength activity index is used to determine whether fly ash or natural pozzolan results in an acceptable level of strength development when used with hydraulic cement in concrete. Since the test is performed with mortar, the results may not provide a direct correlation of how the fly ash or natural pozzolan will contribute to strength in concrete.
