Fly ash and slag in concrete Everything About Concrete

Fly ash and slag in concrete. Hello, I'm wondering how much fly ash or slag is used to replace cement in concrete? If a yard of concrete is roughly 4,000 lbs, my understanding is fly ash might replace 20% of the cement (3,200 lbs cement, 800 lbs fly ash) while slag might replace closer to 50% (2,000 lbs slag, 2,000 lbs cement).
