Re: [papercreters] CMU blocks with crete mortar?

I like the idea.  It seems to me that the gap would just add another air space and help with insulation.  The only problem would be if it feel out of the blocks while moving.  I also get less shrinkage when I add clay and less water! --- On Mon, 2/16/09, Charmaine Taylor <dirtcheapbuilderbooks@gmail.com> wrote: From: Charmaine Taylor <dirtcheapbuilderbooks@gmail.com> Subject: [papercreters] CMU blocks with crete mortar? To: papercreters@yahoogroups.com Date: Monday, February 16, 2009, 2:07 PM Has anyone grouted CMU with papercrete to create a insulated cinder  block wall? What are the pros and cons of this approach? I think that  this would be a great way to build a strong insulated wall that could  be verneered with stone. HI I  have not..but I do know that all PC tends to dry and pull away  and will shrink 10-20% as it is drying, so you will have a gap all over in all spaces of the block.   that said you can come back and pour again, but it adds to the work.  and time to keep filling in the spaces left.    this is a case where a high cement/ low paper  mortar may work better and shrink less.  I hope others have an answer here, it would be a blessing to have a low cost thick mortar of PC to cover and give some insulation value. also the  PC mortar will squish out between layers of blocks, and stay wet inside the CMU  longer than if exposed to some air drying... you may not get the bond you need as mortar SHOULD be giving on a block wall if the CMUs can get wet they will keep the PC wet too, so a  foundation that  does not allow moisture to pass upward is critical. -- Ms. Charmaine  Taylor/ Taylor Publishing Toll Free Order: 1-888-441-1632 www.dirtcheapbuilde r.com   www. papercrete.com         PO Box 375, Cutten CA 95534
