Abstract:
C. A. G. Weymouth’s theory of particle interference postulates that fine particles infiltrate into the voids of larger particles. The authors’ examination of Weymouth’s method of calculation has shown his results to be in conflict with recognized physical laws. They advance a new method of applying the Weymouth criterion for particle interference in concrete mixes, based upon a consideration of the complete grading of solids instead of applying the criterion in turn to each successive size group.
