Has anyone poured or pumped wall forms with papercrete ?
I don't think the formula is that critical but here are the problems i
encountered. i pumped to form 4 inches of pc inside an existing
concret block building.
1- the paper crete shrinks like crazy vertically. so a 8 foot form has
no advantage over slip forming.
2- If there is conduit on the walls or fastened to the form the
shrinking pc hangs up on it and leaves a gap under the obstruction.
3- if the block wall wasn't drilled and bolted to the forms the weight
of the pc bulged the block wall. so the forms for an 8 foot wall need
to be just a strong and ridged as if you where going to pour concrete.
4- i used a 2" trash pump and when it failed i had no back up. because
of the roof on the existing structure i could not even bucket it. but
who is going to bucket 600 gals of pc? the biggest source of pump
problems was blockage from trash in the used paper. sample credit
cards from junk mail bottle caps, plastic binding straps from who
knows where ect.
a larger pump maybe would work but that means moveing a larger hose.
other than the blockages 2 pumps in series really moves the pc
if i were planning to pump pc again i'd have a irrigation gate in the
bottom of the mixer and dump over a 1' screen into a pump sump. and
slip form it.
just where i've been
