benefit of slag and fly ash in concrete composition

FLY ASH CONCRETE . Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix. The main benefit of fly ash for concrete is that it not only reduces the amount of non-durable calcium hydroxide (lime), but in the process converts it into calcium silicate hydrate (CSH), which is the .

ABSTRACT

So far, most researchers utilized the recycled concrete aggregate (RCA) from C&D waste for producing low-strength concrete. Only a few researchers have utilized RCA for making high-strength concrete. The utilization of recycled aggregate (RA) in high-strength concrete has been restricted to 25-30% only because of its poor quality.
