Effect Effect Of Grinding On Sp Gravity Of Cement

Grinding process of cenospheres increases the specific gravity and fineness, and consequently results in higher pozzolanic reactivity of the fly ash , . According to Cornelissen et al. 14 , the use of ground fly ash as a pozzolanic material in concrete production results in higher strengths with no negative effect on workability.
