Re: [papercreters] Re: pressing the paperconcrete

The opposite is actually documented.  Compressing papercrete increases the insulative values per inch.

 

Just so we're all clear . . . the gurus say . . . compressed papercrete is stronger AND more insulative.  As a caveat, I do believe the strength quoted was compressive, not tensile.

Pressing the PC makes it more dense. This compresses the structure and makes it much stronger. Howevver, with the compression can come some loss in insulation as you are removing the air in the block.

 

To test this get a handfull fo PC and make a ball. Bout the size of a softball. Just round it out but do not compress it. Take another ball of PC and start squeezing the bejebbers out of it. Keep adding PC to it until it is roughly the same size as the other ball. Let them dry for 10-12 days and see which one you can pull apart with your hands.
