CONCRETE FOR FOUNDATIONS 
A CORRESPONDENT of the “En- 
^ gineering Record” has been com¬ 
municating to that journal some strange 
notions about concrete for foundations. 
In his opinion, the ordinary practice of 
mixing the cement and sand dry, then 
wetting this, mixing with the washed 
broken stone, putting into place, and 
tamping until a film of water appears 
on the surface, is all wrong. His objec¬ 
tions to this procedure is, as he says, 
that the concrete is thus made too wet, 
and that the tamping, by bringing the 
water to the top, brings up with it the 
cement, “and thus diminishes the con¬ 
cretion of binding properties so neces¬ 
sary to its strength.” His advice is, 
therefore, to mix the sand and cement 
dry, and, without wetting them, to add 
to them the broken stone, previously 
washed, but allowed to drain and then 
put the mass in place without tamping. 
It is difficult to believe that a person 
who could give such advice can ever 
have seen concrete-work done on an 
extensive scale. Every engineer and 
architect will agree with him as to the 
impropriety of “deluging” concrete with 
water; but his ideas of what constitutes 
“ deluging” are most extraordinary. By 
actual measurement of the water used 
in making some thousands of yards of 
concrete, with one part Dyckerhoff 
cement to four parts clean and rather 
coarse sand, and six parts of broken 
granite of the ordinary size, it was found 
that, after mixing the sand and cement 
dry, sprinkling them with a watering- 
pot with twelve gallons of water to each 
cask of cement, turning meanwhile, and 
adding the six parts of broken stone, 
thoroughly washed with the hose, and 
allowed to drain, but not to dry, the 
resulting mixture, when well turned, 
was just about as wet as garden loam, in 
that desirable condition for agriculture 
in which it will not stick to the spade. 
This concrete, when put immediately 
into the trenches, in layers twelve 
inches thick, required half an hour of 
hard tamping before a film of water 
could be brought to the surface, and 
was reduced about one-sixth in volume 
by this tamping. The film of water 
brought up by the tamping was a mere 
appearance of wetness, which was in¬ 
sisted upon simply as evidence that the 
concrete had been compacted by the 
tamping to the desired extent; and it
