construction mud bricks

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

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)?

Comments

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.
