Very favorably. Think of how big a bag of cement is. Using a timber mold like the one used in the video you can leave 100s (if not 1000s) of bricks to dry in

Very favorably. Think of how big a bag of cement is. Using a timber mold like the one used in the video you can leave 100s (if not 1000s) of bricks to dry in one day. You need some materials like clay soil, straw and sand, some which might be sourced on-site. It might take a day or two in hot sun for the bricks to dry, but this can be done in large batches with enough space. They also can be fired in a kiln for extra strength, but that would forgo some CO2 benefits.
- beAbU 3y agoYou know cement is not used to make the bricks right?
