Compressed Earthen Block Production

Step Four: The Slurry

One set of equipment will make 7000 to 8000 blocks per 10 hour day - enough blocks to build nearly three homes per day.

(At Right) We make the slurry from local soils, water and a proprietary polymer.

All we need to do is PAINT or POUR the slurry onto the top of the blocks. No need to use mortar, which is essentially the weakest part of the block wall.

Slurry Test

Pouring the slurry onto the block surface is five times faster than applying mortar to the blocks. This significantly reduces the cost of labor as specialty labor is not required

 

Compressed earthen blocks do not require skilled mortar technicians to install them.

(At Right) Slurry Test - a thin slurry is made using the same material and poured onto a base block. Another block is placed on top and a 3 inch nail hammered into the top. After 4 minutes you should be able to pick up both blocks by the nail. The slurry creates a bond that is 2.5 times stronger than a mortar bond.

Compressed earthen blocks do not require skilled mortar technicians to install them.

 

(At Right) This shows a block with two discs of slurry that dried overnight and could not be peeled off. They broke when you tried to remove them.

When using a “Like” material (the same soil as in the blocks) the bond is stronger. And in 24 hours you have an unbreakable wall.

 

 

(At Right) This shows what happened if the slurry disc was forced and broken off.
