Jan 07 1999 At an equivalent 28-day compressive strength concrete containing fly ash typically achieves a lower 7-day strength compared to concrete without fly ash. However an equivalent early-age strength can be achieved with the use of accelerators water-reducing admixtures andor by modifying the mix proportions.

The Effect of Eggshells Ash on the Compressive Strength

The concrete specimens were tested in the series of compression test to determine the strength of concrete for 3 7 and 28 days. As a result the additional of eggshells ash to the concrete mix increase the strength of the concrete. In short the higher percentage of eggshells ash in the mix means a higher compressive strength for the concrete.

STRENGTH fly ash

In general a relationship exists between the compressive and flexural strengths of concrete. Concrete which has a higher compressive strength will have a correspondingly higher flexural strength. This holds true for fly ash concrete. However in many cases fly ash concrete has demonstrated flexural strength exceeding that of conventional concrete when compressive strengths were roughly equal.
