Abstract:
Dolisie, 3rd city of the Republic of Congo, since the colonization, the constructions are realized
much more with the bricks cooked to the detriment, the block work and compressed earthen
brick (BTC) or brick stabilized. Although less expensive (25 to 50 CFA francs) compared to the
other two whose prices vary between 350 and 475 CFA francs, the production of the baked brick
has effects on the urban environment of Dolisie city. Thus, evaluating these effects is the
objective of this study, whose methodological approach is summarized in three phases:
documentary research, fieldwork and laboratory phase. The results obtained show that the
production of baked brick has ecological advantages (thermal insulation, durability, internal
humidity, water proofness and aesthetics). Despite this, we can see that there are many negative
impacts related to the production of the baked brick, thus compromising the sustainable
development of the city (destruction of the urban space by the crevasses whose earth losses are
evaluated between 1,473.7 and 3,445.9 tons thus slowing down spatial growth, urban mobility
and creating growing insecurity in the neighborhoods concerned).
