Re: [TowerTalk] The tower base is poured BUT...

[Red <RedHaines@centurytel.net>]

Hi, all;

David Robbins mentioned free-fall.  To add detail, free-fall and 
excessive vibrating or stirring causes the aggregate to separate.  The 
large pieces go to the bottom, the fines, including the cement, separate 
and rise to the top.  The result is not  a homogeneous mixture of 
aggregate and cement and its strength is not uniform.

Confer with a knowledgeable professional regarding the limits.
