Hi John,

1 -- Am I correct that whenever you say 7-8%, you mean by volume?

2 -- Could you post the details of the mixtures you are using? What sizes and how much of each size? What epoxy/hardener?

3 -- It would be great if you could send some samples to ckelloug so that he could measure and tell us the physical properties? (I believe that Cameron has offered to do this?)
