Abstract:

A rising concern in today’s construction industry is environmental responsibility.

The addition of fly ash is a leading innovation in sustainable design of concrete. Fly ash,

a waste by-product of coal burning power plants, can be used to replace a portion of the

Portland cement in concrete. Investigators are pushing for higher and higher total

replacement levels in what is known as high-volume fly ash (HVFA) concrete. However,

minor issues observed with lower fly ash replacement levels may be exacerbated as the

levels increase.

Before the implementation of any new and innovative concrete, a new mix must

be subjected to a series of tests and then compared to a conventional concrete mix that

was subjected to the same test. In this investigation HVFA concrete was subjected to

mechanical property tests such as compressive strength and modulus of elasticity as well

as durability tests such resistance to freeze-thaw and chloride penetration. After being

subjected to these tests, the HVFA concrete was found to be comparable to conventional

concrete except for salt scaling.
