Benefit Of Slag And Fly Ash In Concrete Composition

: Benefits of slag and fly ash - ScienceDirect
1996-7-1 · Slag or fly ash containing concretes will also have a lower lime content than Portland cement concretes. Thus the amount of material to be carbonated is lower. These factors explain the higher carbonation rates observed in labo- ratory experiments in which the concrete is stored at constant humidity and temperature.
