Appendix - Concrete Mix Information - MULTIQUIP MAYCO LS600 Operation And Parts Manual

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.
