CONCRETE MIX INFORMATION
The following information has been extracted from actual testing laboratory reports. The purpose of this printing is only
to help create a better understanding of the importance of uniform gradation and proportioning of materials which affect
pumpability of concrete mixes. These weights and proportions illustrate that when the sieve analysis is ideal, the sand/
rock ratio can be adjusted (65% sand 35% rock) and pumpability should be excellent.
