That's a mere 67.5 tons! A heavily burdened single axle dump truck can handle 10 tons so we are up to almost 7 dump truck loads. For 4500 adobes each weighing about 30 pounds you will need 135,000 pounds of material. Does anybody near my area carry bags of material to make bricks myself that I can just "add water" to?Ī: I don't think anyone has it bagged. I think I have the patience to make all the bricks myself (good estimate of about 4,635 bricks for five foot height). Q: I live in Santa Fe, NM and am interested in constructing a wall around my property made of adobe bricks. But the drop test does all that you need to know. Now, probably the whole EU uses the tests. Germans do and it's in their DIN Standards. We never bother with a test for hardness. Basically if you have a frame to fit them into, as long as you can pick them up and get them into the frame, they will work. If they break you might be lucky and can use halves or thirds to fill in smaller spaces. If the bricks survive, they are good bricks. Once a few test bricks are made you can test them for compressive strength and at the same time for modulus of rupture by dropping them from knee height. Once stacked they should dry/cure for four weeks before use. Then stack them out of the way so that you can make more bricks. On edge they need about a week of drying. If they don't like to balance on edge, do a herring bone pattern with them touching each other to stay up. As soon as they can be turned on edge, turn them on edge.
Let the bricks dry in the sun for a day or two. When the form is lifted, if the bricks slump down, then just put them back in the wheelbarrow or mixer and add more dirt to stiffen it up.With adobe there is always a second chance.
With one form which has to be pulled right away to get ready for the next load, then the adobe mud needs to be stiffer. Worldwide most folks only have enough wood to make one form for four adobes and that is just about the amount that comes out of a worldwide standard wheelbarrow. It can be pretty slurpy if you have enough forms so that you can leave mud in them overnight to start drying and then pull the forms the next day. And that judgement comes quickly after several tries. The best measure of water is your judgement of what is workable. I would have just gone up the wadi and gotten sand and forgotten about Pharaoh's straw.

Too much clay and the bricks crack and that is when you need straw and that got widely publicized by Moses up in Egypt. The best test is to make some test bricks. The jar test is rarely straightforward and easy to read.
Q: What is the best mix for good adobe blocks?Ī: Mainly you want 30% clay or less. His website,, lists the course schedule and many other resources related to working with adobe.
