“…Due to limited availability of natural resources and rapid urbanization, there is a shortfall of conventional building construction materials. Therefore, study has been conducted by many researchers on the use of agricultural waste as partial construction materials either cement, sand or aggregate [7][8][9][10][11].…”

Abstract. The use of brick in construction is commonly used, especially in the construction of buildings and infrastructure. Various studies have been conducted to produce methods that can increase the strength of brick at the same time can reduce the cost of manufacturing bricks. In order to reduce cost of manufacturing, one of the solution applied was by using waste as part of bricks production materials. In this study, sugarcane bagasse (SuCaB) ash was used as a part of compressed earth brick (CEB) by replacing the quantity of cement for SuCaB ash. The study focused on the physical and mechanical properties of CEB containing SuCaB and the optimum percentage of SuCaB ash as partial cement replacement in CEB. There are 4 types of percentages used; 0%, 20%, 25% and 30% from cement content. All mixed use the same water content of 30% of cement content by weight and the ratio for cement: laterite soil used was 1: 6. A total of 72 specimen with size of 100mm x 50mm x 40mm was produced. The test conducted were Initial Rate Absorption Test (IRA), Density Test, Dimensions Test, Compression Test and Water Absorption Test. From the experimental results, the optimum SuCaB ash percentage as cement replacement in CEB was 20%. It recorded the highest compressive strength of 16.23 MPa at 28 days while for the Initial Rate Absorption test, it lies within the range specified. The density of CEB containing 20% of SuCaB shows slightly lower value where it decreased for about 0.4% from the control specimen. From this study, it can be concluded that waste materials such as sugarcane bagasse can be used as part of construction materials. However, further study needs to be conducted such as on the energy consumption, chemical properties and others to enhance the knowledge on this area before it can be applied into the brick production.

In this study, ash from sugarcane waste was used in the synthesis of biosilica using alkaline extraction followed by acid precipitation. Different parameters that could influence the silica particle synthesis were evaluated. The ash and synthesized biosilica were characterized by a combination of spectroscopic and chemical techniques such as XRD, XRF, SEM, particle size analyser, N 2 adsorption analysis, TGA, and FTIR. The best condition for biosilica production was achieved with fusion method and aging temperature of 80 ∘ C for 1 h during gel formation. X-ray powder diffraction pattern confirms the amorphous nature of synthesized silica. The purity of the prepared silica was 99% silica which was confirmed by means of XRF. The experimental data suggest that the sugarcane waste ash could be converted into a value-added product, minimizing the environmental impact of disposal problems.

“…Essa mudança no processo das indústrias sucroalcooleiras pode significar um incremento de custos que dificulte a agregação de valor à CBC. A homogeneidade na produção das cinzas não pode ser exigida do processo industrial, que raramente possui controle operacional da temperatura de combustão e do resfriamento das cinzas (SALES;LIMA, 2010). Realizados dessa forma, sem controle, esses procedimentos tendem a produzir cinzas sem reatividade hidráulica.…”

“…A crescente elevação do custo da areia natural abre espaço para a entrada de outros materiais, como os resíduos, sendo esses de custo bem inferior aos correlatos naturais (SALES;LIMA, 2010). A CBC tem se mostrado um subproduto viável para aplicação em materiais de construção, desde que sejam observadas suas características intrínsecas, como o alto teor de sílica em forma de quartzo, um dos principais elementos presentes na areia natural (CORDEIRO et al, 2008).…”

Resumobagaço é gerado como resíduo do processamento do açúcar e do álcool. Esse resíduo é utilizado para a cogeração de energia por meio da queima em caldeiras, restando ao final as cinzas residuais do bagaço da cana-de-açúcar (CBC). Atualmente, essas cinzas são aproveitadas nas lavouras de cana como adubação orgânica, apesar de ser um material com poucos nutrientes. O objetivo deste trabalho foi avaliar a durabilidade de concretos que utilizaram a CBC em substituição ao agregado miúdo por meio de ensaios de carbonatação e abrasão. Os resultados foram comparados aos obtidos para um concreto sem CBC. Os concretos foram dosados para que tivessem a mesma consistência e o mesmo teor de argamassa. Produziram-se traços com 0%, 30% e 50% de CBC, em substituição ao agregado miúdo em três grupos diferentes. Foram realizados ensaios mecânicos e, a partir dos resultados obtidos, os concretos que apresentaram os melhores resultados foram submetidos ao ensaio de carbonatação, nas idades de 60, 120 e 210 dias, e ao ensaio de abrasão superficial, aos 28 dias. Os resultados obtidos permitiram concluir que a carbonatação e a abrasão do concreto produzido com a CBC como substituto parcial do agregado miúdo e o cimento CP II E 32 são similares ao concreto sem adição da cinza.
