STRENGTH OF CEMENT MORTARS 147 Figs: 51 and 52, page 145, illustrate the use of the triangle for showingthe volumes of sands composed of different sizes of grains. Any sand,for example, whose granulometric composition is represented by any pointon the contour line labeled , i^^ Fig. 51, has, when measured loose, of it^ volume, or 57^%, of absolutely solid matter, or, taking thecomplement, 42^% of voids, In Fig. 51 it will be seen that the greatest soHdvolume of loose sand is obtained by mixing G and F in proportions 60%
