Dust deficient aggregates always produced less workable concretes for cement contents below 330 kg/m 3. These concretes were also less strong than the others. As a result for this particular case, minimum cement content of 330 kg/m 3 is recomended for concretes produced with dust deficient aggregates, instead of the common minimum of 300 kg/m 3. Additional cement seems to compensate for the missing dust …
