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).
