Re: [papercreters] Re: The uninformed

I agree - from the DIY side.  THe CEB block engineer that I worked with did a series of structure tests.  It cost him $1000.  The problem he ran into was CEB is not a certified material and every time he went to build blocks he had the same test expense.  Concrete must be tested but that seems to be easy and they have a lot of data.  Can papercrete be tested as concrete.  Can the mix be consistent?
 
A missionary built 50 CEB forms in  a grid.  Covered with Lid with inserts to ram the material.  Then he parked a truck on it.  It worked with "damp" CEB.  How much preasure do we need?  WIth CEB we are binding through extreme preasure.  Papercrete?

per square inch? How far can you compress papercrete - 2 to 1? If
you squeeze out all the liquid does this ruin the block. How long do
you hold in compression?

experimented with what Papercrete needs? CEB presses are over kill
for papercrete? I have a 30 ton press for CEB. - 2 to 1 material
ratio - is this overkill for papercrete?

Well that is something we will have to experiment with but common
sence tell us that we just want to remove some of the water to keep
the r factor.We have a 50 ton loader from our pit if we can park it
on 4 bricks and they hold i think they will be ok lol.In the meen
time we will have to just have to try differnt pressures till we get
it right.Thats the fun part of doing a project like this gets the
brain going .Clair
