Fly ash and slag ScienceDirect

Low-calcium (FA) and high-calcium (HCFA) fly ash and granulated blast furnace slag (GBFS) are the most widely known, standardized and used SCMs in the composition of cement and concrete. In the last 4 years, scientific work has focused on improving binder properties (e.g. long setting time, low early strength etc.) containing large quantities

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.
