This misconception about concrete cutting arises largely from the habit of thinking of concrete cutting solely in terms of certain arbitrary proportions, in which case, of course, the only way to change the consistency is to change the water content. Once the habit of relating all discussions of concrete to experience with 1:2:4 or other fixed proportions is thoroughly shaken off, it is seen that control of the quantity of water means simply fixing the potential quality of the concrete. Thus, with the water quantity fixed in terms of the cement, the consistency must be controlled through the relative quantities of concrete aggregate and paste and proportions of fine to coarse concrete aggregate. Naturally, the consistency to use depends upon the requirements of the work; the concrete should be sufficiently mobile to mold properly, but not of such fluidity that the material will segregate either in placing or through settlement after once in place.  The detailed study of the principles which have been briefly outlined in Chapter I may well begin with the consideration of the part which the water plays in the making of concrete. As brought out in Chapter I, the proportion of water to cement is one of the three factors which determine the quality of the paste.

This water- cement ratio was also shown to be a significant factor in the consistency of the concrete, affecting to an important degree the workability of the mixture. Thus, we see that the water serves both as a chemical constituent of the active paste and as a vehicle to make the concrete more readily workable. The two-fold purpose of the water is nicely brought out by the diagrammatic representation in which five mixtures are shown all mixed with sufficient water to give a uniform consistency slump 3 to 4 in. The mixtures selected-1:1:2, 1:1-:3, 1:2:4, 1:21:5, and 1:3:6 required respectively, 4, 5, 6, 8, and 10 gallons of water per sack cement to give this 3 to 4-in, slump. It must not be assumed that these mixtures all have exactly the same workability because they have the same slump, for this is not possible with such a wide range in cement content. It can be seen, however, that for certain types of work, as for example, a masonry wall or footing, these mixtures could each be used satisfactorily. This fact must be kept in mind, for the full significance of the study in Fig. 1 would be lost if the mixes were not comparable on some basis. The basis here adopted is that they might, so far as workability is concerned, be equally suitable for some class of work. The comparison then can be fairly made as to their relative suitability, considering strength, water tightness, and cost. Neither should it be assumed that because the familiar arbitrary mixtures have been used in this illustration that these are necessarily the most suitable.

These have been selected as they are most familiar to those experienced in concrete work. With these particular concrete aggregates, as with most others, slightly higher proportions of the fine concrete aggregate with respect to the course would prove more suitable for the ordinary concrete work. However, the mixtures all had sufficient paste to completely fill the spaces between the concrete aggregate particles and with care could be used in mass construction. The interpretations from this diagram, to follow, and any further references to it in the text can be applied to concrete mixtures as a whole only when the concrete has been so placed as to avoid separation or segregation of the ingredients, and to give a mass that is uniform and homogeneous with all the spaces completely filled with paste. The abscissas in Fig. 1 have no significance. The mixes are merely spaced equally.
