“…A typical mix of the soil-cement brick before the curing process takes 7 to 10 parts in volume of sand-based (50 % to 70%) clay (30% to 50%) soil, 1 part of Portland cement [39,41,42], and water as much as 5% to 20% of the mixture bulk mass depending on the soil [43]. Average values were used for the soil-cement baseline scenario.…”

Masonry wall is a key construction subsystem, but it embodies significant environmental and energy burdens within the life cycle of buildings. Soil-cement bricks and blocks stand as an alternative low-cost masonry material, but despite the widespread claim to be environmentally friendly, more systematic investigation is lacking. This study aimed to assess the life cycle environmental and energy performance of 1.0 m2 of a soil-cement brick masonry wall from cradle-to-construction in terms of carbon, energy, and water footprints, and fossil and mineral resource use, as well as compare it with conventional technologies such as ceramic and concrete block masonries in Brazil. Results showed that raw materials are a major contribution to soil cement masonry walls, followed by the joints and links with columns, in which cement stands out among other inputs. Hydraulic pressing in brick production had a negligible burden increase compared with manual pressing. The PVA mortar joint outperformed the PVA glue one, whereas resin coating performed better than cement mortar. In comparison with ceramic and concrete masonry walls, the soil cement masonry presented overall better environmental and energy performance and was the least affected by the inclusion of finishing coating layers and transport of materials in the sensitivity analysis scenarios, although improved scenarios of conventional options could be competitive, e.g., ceramic masonry with blocks produced by firing reforested wood for the carbon footprint. Scale-up analysis revealed that widespread deployment of soil cement masonry in the built environment would substantially avoid environmental and energy burdens compared with conventional technologies.

“…É oportuno destacar que tecnicamente o tijolo de solo-cimento é um compósito oriundo da mistura de cimento e solo (esse, por sua vez, geralmente é constituído de 70% de areia e 30% de argila) visando produzir alternativas sustentáveis e mais econômicas para a construção civil [13].…”

Este trabalho investigou a elaboração de composições de tijolos de solo cimento a partir dos resíduos da construção civil (RCC) e do beneficiamento do caulim (RBC) do Amapá. Um solo artificial foi previamente preparado a partir da mistura desses resíduos, produzindo, então, um solo artificial que foi aplicado na formulação de três traços (cimento:solo artificial):1:10, aplicado como controle, e as variações 1:12 e 1:4. As matérias-primas foram caracterizadas via difração de raios X (DRX) e os tijolos foram testados quanto à resistência à compressão (RC) e absorção de água (AA) após cura durante os períodos de 3, 7 e 28 dias. Aos sete dias de cura todos os blocos formulados apresentaram resultados médios promissores conforme as recomendações da NBR-8492 (mínimo 2 MPa para RC e AA inferior a 20%), os menos resistentes com 2,75 MPa e AA de 17,35% para o traço 1:12, e os mais resistentes com 6,67 MPa e AA de 13,76% para o traço 1:4. O aumento do teor de cimento e do tempo de cura melhorou as propriedades avaliadas, indicando que todas as formulações apresentam potencial para a produção de tijolos de solo-cimento.Palavras-Chave: Solo-cimento; tijolo ecológico; resíduo; caulim.
