Hi to everybody;
I´m writting to all of you who believe in dreams.
Now i´m trying to realize mine. its about my professional tesis. I studied architecture and want to apply the use of papercrete in houses to poor people in my country. I´ve read almost everything about it and now is the time to make it real. In a short time I´ll move to the town I choose for this application and want to share every step with you all.
The most difficult item isn´t constructive or technologich, iT´S TO MAKE PEOPLE UNDERSTAND PAPERCRETE IS A CONVENIENT MATERIAL. If anyone has make has made a similar aplication please contact me. Otherwise i´ll keep in touch to share my experience and hear all your suggestions.
A very huge hug.

Correct me if I'm wrong, but it seems to me that its not a convenient material, and that's one of its issues. To use it one must make pulping equipment, and the time, trouble, cost and expertise required for that is simply beyond most people.

Dear Marco,
I am trying something similar here in Pune, India.
The first step I am taking is to get the raw material cost of one cubic foot of papercrete mix below the wholesale price of one cubic foot of conventional bricks.
This is tough to do as used newsprint as other economic uses in India and sells at four times the cost of rock aggregate that it replaces in concrete.
Second I am trying to get a good engineering college to certify the strength of the bricks produced.
Thirdly I am looking at uses such as making chicken coops (in good demand) rather than making houses in which people live. Just imagine a conversation between yourself and your wife where you tell her that the first house that the family will own is made of paper!
Let us see how it goes.
Regards
Ashok

Have you tried using tetrapaks in place of paper? I havent tried it, but I seem to remember hearing someone that managed to get it to work. I assume they'd be harder to pulp, and might need chopping before pulping. They have far lower value than paper.

If possible do not use Newspaper because of it resale value, surely there are places that pay to have their paper shredded, show them that they don't have to pay for that service, that you will soak that paper in water and pulp it for free. Also don't produce bricks or blocks, pour the walls in place there by saving a lot of time and labor. Yesteday I had to cut out a section of wall about 6 inches tall and 12 inches wide and 12 inches long, to make room for a new window. I had never had to cut my mixture before and I've seen demo's on the net as how to do it with a chain saw. Well let me tell you my mix must be much stronger that the ones I've seen cut on the net, it took me about 20 minutes and three tries before I got the small section cut out, I was shocked at the weight of such a small piece of block, I have not weighed it yet but I'll bet that small section will top 20 lbs., and it had been dry for a year now. I calculate it takes about 10 gallons of cement to pour a 12" tall 8" wide by 12 feet long and that calculates to about $10.00 for less that $1.00 per sq ft of wall, can't see how you can get much cheaper.

They're a laminate of paper card lined with plastic film and aluminium foil. Their mixed composition makes them not recyclable by any of the well known means. But they're mostly paper, so could make papercrete with only a slight strength reduction. They'll likely need a clean. And of course theyre thrown away in massive quantities.

Dear NT,
To my knowledge, Tetrapack cartons are usually lined with plastic or aluminum foil.
See the following extract from Wikipedia :
https://secure.wikimedia.org/wikipedia/en/wiki/Tetra_Pak
Tetra Pak's first product was a paper carton used for storing and transporting milk. The first product was a package in the shape of a triangular pyramid (or tetrahedron), called the Tetra Classic. Ruben Rausing and his team had been working on the Tetra Classic design since 1944, and by 1952 had perfected techniques for making his cartons fully airtight, using a system of plastic coated paperboard.
The lining will cause immense grief as cement will not stick to it and the output will have poor strength.
That said I have not practically used Tetrapack in papercrete.
Regards
Ashok

Dear Countryatheartok,
That is a great name!
Certainly I am trying to minimize the use of newsprint.
It is known to me that A4 size magazines use superior strength newsprint and therefore form a much better base for papercrete.
They also resell at a per kilo rate that is half of old newsprint. They are the first replacement that I will pursue.
One reported problem with their use is that the spine contains whit adhesive glue that is waterproof and will need to be removed before pulping the magazines.
Similarly metal staples need to be removed.
Used Cardboard boxes of varying strength are readily available in the reused market. They provide good pulp replacement for newsprint.
Rice and Wheat straws that are available after harvesting of the main crop are another cheap source of wood fibre.However without experimentation, it is not possible to say what sort of strength is obtained when newsprint is partly replaced by them.
A material that has not been discussed in any great details in this forum is rice hull. All by itself and cement, the resulting mix crumbles quite easily. How it will behave when mixed with newsprint is yet to be tried out.It has other properties that excite me to try it out.
Regards
Ashok

They're lined with both ali foil and plastic film. The plastic provides a wipe clean surface, reliable waterproofing and makes it heat sealable, and the ali provides a vapour barrier.
The percentage of these is very low, but its your call if you dont want to try it.

Yes my recipe for cement is the same as concrete that is one part cement
for every 3 parts paper and 2 parts clay or sand. But cement does not
weigh all that much that small one part cement might weigh 9.4 lbs I
come up with that number by taking the weight of a bag of cement (94 lbs
and dividing it by 10 or about 10 gallons of cement to the 94 lb bag) I
suspect the clay weighs much more than the cement and there is twice as
much. And there is three times as much paper but it only weighs about
the same as the cement. What are you calling the right amounts of clay
and pulp? Is that a 50/50 mixture? And how water proof is that mixture?
I tried clay and pulp last year left it out in the weathe along side my
mixture and it turned to mush in about 6 months. My mixture is still
hard and firm, soaks up water if left on the ground but will dry out and
remains hard all the time.

they don't have to pay for that service, that you will soak that paper
in water and pulp it for free. Also don't produce bricks or blocks,
pour the walls in place there by saving a lot of time and labor.
Yesteday I had to cut out a section of wall about 6 inches tall and 12
inches wide and 12 inches long, to make room for a new window. I had
never had to cut my mixture before and I've seen demo's on the net as
how to do it with a chain saw. Well let me tell you my mix must be much
stronger that the ones I've seen cut on the net, it took me about 20
minutes and three tries before I got the small section cut out, I was
shocked at the weight of such a small piece of block, I have not weighed
it yet but I'll bet that small section will top 20 lbs., and it had been
dry for a year now. I calculate it takes about 10
gallons of cement to pour a 12" tall 8" wide by 12 feet long and that
calculates to about $10.00 for less that $1.00 per sq ft of wall, can't
see how you can get much cheaper.

Dear Marco,
I am trying something similar here in Pune, India.
The first step I am taking is to get the raw material cost of one cubic
foot of papercrete mix below he wholesale price of one cubic foot of
conventional bricks.
This is tough to do as used newsprint as other economic uses in India
and sells at four times the cost of rock aggregate that it replaces in
concrete.
Second I am trying to get a good engineering college to certify the
strength of the bricks reduced.
Thirdly I am looking at uses such as making chicken coops (in good
demand) rather than making houses in which people live. Just imagine a
conversation between yourself and your wife where you tell her that the
first house that the family will own is made of paper!
Let us see how it goes.

Dear Countryatheartok,
May I suggest that you try a small experiment using only half the quantity of clay and sand that you are presently using.
From what I have read, about 10% by weight of sand/clay gives the optimal strength and R values. Also the blocks remain light wieght.
Try it on a few blocks and let us know wht you find.
Regards
Ashok

I don't make blocks, I pour my blocks as seen above, this was my very first try at pouring in place, they are called "T LOX-BLOX" why waste time making blocks that have to dry before you can lay them and then you have to make a batch of PC to lay them with, when it is so simple to just pour the blocks in place and be done with it, they can dry in the wall and they do that really fast with my formula.

The photo of the first T lock Block is showing the form removed on one side to show how the T Lock is made, the form was removed the next morning, the block was poured the early evening before and dried overnight. An even faster way to pour PC is the slip form method shown below, I have modified it by not sliping the one form up but by adding more forms on top of the first until I reach the wall height I want.
Next photo is a close up of how it looks after the forms are removed and how well the half wall ties to the full wall.
