Report on environmental impacts of concrete mixing plants

ENVIRONMENTAL IMPACT OF CONCRETE

a more common use is in concrete mixture as a substitute for some of the cement. Fly ash, or pozzolan, can readily be substituted for 1535% of the cement in concrete mixes, and for some applications fly ash content can be up to 70%. Fly ash today accounts for about 9% of the cement mix in concrete. Fly
