[papercreters] slip form vs fast dry

Hi Dan,  if the thicker panels you want won't be dry in time < 4 weeks then  could you just go ahead and pour lots of smaller blocks?

In Oregon at Lost Valley community they  made pump house blocks on the ground,  slightly elevated on screens or scrap wood I think,  enough to get air to flow under, and then laid cement blocks with sheets of glass over to hurry the drying with solar help.

with a stack of thick vertical panels you'd  have the bottom being wet the longest as the water drains

I made 4' long x 16" wide by 4" thick panels  by pouring wet slurry onto wire bakery trays* lined  in newspaper sheets, and dried in the sun. ( with glass over top, it rested on the edge of the plastic coated frame  I cut them into   the size blocks I wants while still a bit green, and they dried  faster with the  cut ends exposed too.   they dried in less than 4 weeks, and it is never very sunny here so we have foggy weather, limited sun, cool summers.   it is the thickness that will slow down curing.

sandwiching  thinner panels together will give 12" thick

these are plastic coated  wire units meant to transport bread loaves in delivery trucks, they  are open on the ends ( which I blocked with scrap wood pieces)   having an open frame form helped dry them too, as the newspaper wicked water away, and dried in the sun where a  plywood form would hold water longer

i'll dig up a pic and send it to you
