SHOULD PORTLAND CEMENT BE DISPERSED?

A DEVELOPMENT OF DEFINITIONS OF WETTING AND DISPERSION IS FOLLOWED BY A DISCUSSION OF DISPERSION OF PORTLAND CEMENT. FROM ELEMENTARY PRINCIPLES IT APPEARS THAT A WETTING AGENT IS UNNECESSARY, FOR PORTLAND CEMENT IS HIGHLY HYDROPHILIC. ARGUMENTS ARE SET FORTH REGARDING THE POSSIBLE UNDESIRABLE EFFECTS OF CEMENT DISPERSION ON THE BLEEDING AND RHEOLOGICAL PROPERTIES OF THE PASTE. /PCA/
