affect of c2s on cement grinding

  • Effect of Particle Size on the Properties of Cement Paste

    FINENESS OF grinding constitutes an important variable in the behavior of portland cement. Everyone is well aware of the opinions often quite acrimonious that have been expressed about finely ground modern cements in contrast to coarsely ground old-fashioned cements. This paper is concerned with the properties of the ground products.
