RE: [papercreters] Re: pumice-aggregate leave out?

Judith that is the direction I’m leaning right now as well.  I bought some earth bag and rammed earth books this summer but it likely won’t be till next summer that I start playing with it.  My soil is a very high clay content soil.  I have some sand in a low area that I can dig out as well, but it is very fine (I worry too fine).  For rammed earth they typically call for only 25% clay and the rest aggregate.  But I think mine will be almost the reverse so I hope by adding some lime and a bunch of paper fiber things will work well.  I am also leaning towards slip forming.

So you just use clay dirt and cardboard? I wonder if I should do that in stead of cement. When I first made blocks a few years ago I did a batch with soil and paper but found they took a very long time to cure and were heavier than the ones made with cement. How much soil do you put in? I have reduced my cement to 1/2 bag per 200 gallon mix. I'm sure that if I used soil I would have to put more in. But I do like the idea of using soil because it's free and green. I am also now using cardboard since the newspaper plant locked up their bins. I cram them into a 55 gallon drum and soak them for a day or so. Is that how you do it? I am starting a new project in a couple of weeks and plan to slip form the whole thing. I would like to use the soil so I guess I'll give it a try. I'm also thinking that the color would be nice and if the walls come out nice and even I wouldn't even have to plaster them. What do you think?

Sincerely, Judith

I believe that Eric Patterson made his PC with just cement and pulp and it seemed to work well. Also in Solbergs Building with Paper Crete and Paper Adobe book he described Shorty Ingerhalls PC logs as being made only with pulp and cement. What I have found in my mixtures using the cardboard pulp and the very fine clay soil that I have on my property is that when I add aggregate which is road base screenings with small gravel and very little sand and some clay dirt is that the aggregate tends to settle to the bottom of the mixer and the resultant blocks from the bottom of the batch have more agg. in them and are heavier and the ones made from the top of the mixer load have less aggregate and are therefore quite a bit lighter than the ones from the bottom of the batch. The lighter blocks seem to be just as strong and are lighter and much easier to handle so when I get my mixer tweaked a little more I'm going to make a batch with only clay and pulp and no cement to see how that works. These aforementioned blocks were made with no cement. The blocks that I made with cement in the batch were softer as the cement and the fine clay that I use don't seem to do well together and I really feel that I don't need cement with them. Greener and cheaper blocks but very durable and strong.
