construction mud bricks

related country: Congo

I am looking for (construction) ideas to improve the drying of freshly made mud bricks during the rainy season in the "Bas Congo" Julien

1 Answer


I'm guessing these are sun dried bricks, and the area is to large to be covered with a roof or more temporary cover (plastic)? Do we know what percentage of the drying time needs to be exposed to full sun?

I have seen bricks stacked and covered with polythene for drying in Indonesia - are the bricks sufficiently strong when wet to be stacked?

How open is the community to change - could you introduce something like compressed earth block (which can then be stacked dried as above)?


yes these are compressed earth blocks, I am still trying to find out what the production process looks like. In the rainy season the relative humidity is very high, slowing down the drying process. I am thinking of a shelter with open roof to create a natural ventilation, speeding up the drying time and protecting the blocks against the rains. I never did that before, so I am looking for similar experiences, low cost construction ideas, ..., Julien

I would wonder whether solar drying would be more effective than natural ventilation. Even with really high humidity, if they get a hot sunny day, then I would expect things would dry out pretty quickly. If they are stacking the bricks, then they would have to lay the bricks out for the last few % of moisture removal.
