Abstract:
The authors investigate whether the influence of the water-cement ratio on strength arises simply from the fact that a part of the mixing water produces voids that weaken the mass of hydrated cement paste; or whether there are other more fundamental factors involved. To resolve the problem, not only the hydrated cement paste but also the mortar or concrete containing this cement paste has to be considered. In this connection, it is useful to look into the relation between the strength of mortar and of concrete, both containing the same cement paste.
