t upon the percolation, the wetter concretesheing the- more irapermeahle. Disk #10 containing Qfo of water show-ed a total percolation of 89 grams in seven days, while disk #11containing lOfo of water showed hut 35 grams in the sane period.There are two possihle explanations fo this phenomena- The first is that vhsn an excess of ^vater is used, that water buhhles areformed surrounded by cement, which offer resistance to water enterinf^ from the outside* The second explanation is that 8/b of wateris not sufficient to lake a thoroughly plastic concrete, and thatall of the sand grains and pieces of stone are not coated withsufficient cement grout* The writer ^^elieves that it is possi>>le to decr^ase if notentirely eliminate the displeasing effects caused hy the seepageof water through concrete hy a correct proportioning of the comentsand, stone and water as detemined hy the naxinum density curve,although the tests made were not sufficiently extensive to warrantthis conclusion.
