Potential use of sugarcane bagasse and bamboo leaf ashes for elaboration of green cementitious materials

Production of Sustainable Construction Materials Using Agro-Wastes

“…Additionally, mechanical tests, X-ray diffraction, isothermal calorimetry, and thermal gravimetry analysis were also used in examining the impact of ashes on the hydration of the different cementitious pastes. The findings obtained showed that ternary mixtures of BLA and SCBA had higher pozzolanic activity than the binary mixture of SCBA only [37]. Furthermore, it was also observed that higher compressive strengths were recorded for the binary and ternary mortars than the control mortar, which did not have such additives.…”

“…Likewise, Fiorelli et al [64] showed that the mechanical properties of the particleboards using an admixture containing vegetable fibers were superior to those that only used sugarcane bagasse. With the green concrete production, it was also observed by Rodier et al [37] that cement pastes made from ternary mixtures of bamboo leaves ash (BLA) and sugarcane bagasse ash (SCBA) had higher pozzolanic activity than the binary mixture of SCBA only. Fiorelli et al [64] further showed that manufacturing multi-layer particleboards using an admixture of sugarcane bagasse and Amazonian vegetable fibers such as jute and curaua produced boards with better mechanical properties than those produced using only sugarcane bagasse in their outer layers.…”

“…In a separate study, Rodier et al [37] investigated the impact of adding sugarcane bagasse ash (SCBA) and bamboo leaves ash (BLA) on the pozzolanic and hydration qualities of cement pastes.…”

“…Directly, this suggests that manufacturing green concrete by replacing cement by more than one type of agro-waste material has a positive impact on the features of the concrete. Rodier et al [37] also revealed that less energy was consumed during the production of 1 tonne of binder using agro-industrial ashes as compared to conventional cement.…”

Assessment and Evaluation of Blended Cement Using Bamboo Leaf Ash BLASH Against Corrosion

“…The deterioration due to corrosion of steel reinforcements significantly affects the durability of concrete structures [11]. When the corrosion of embedded steel reinforcement is initiated, it is difficult to stop its propagation, which affects its safety, loading capacity, and service life [12]. Corrosion causes a reduction in the steel bar area and bond strength between steel and concrete [13,14], which leads to cracking, spalling, and delamination of the concrete cover [5].…”
