“…e flexural strength at higher replacement level (20%, 30%, and 40% SCBA) reduced by 15.5%, 28.8%, and 42.5%, respectively. According to available literature, the increased tensile and flexural strength at 10% SCBA may be due to the microfibrous nature of SCBA, which is related with CSH formation, and also due to the formation of aluminates, resulting in needle-like structure [80,81]. e interlocking of these needles takes place between hydrated paste and may directly enhance the tensile and flexural strength.…”

“…e interlocking of these needles takes place between hydrated paste and may directly enhance the tensile and flexural strength. In short, the enhanced properties may be due to formation of more hydrated products, less porous structure of concrete made with SCBA, and the enhanced interfacial transition zone (ITZ) [80,82,83].…”

In this research, multiexpression programming (MEP) has been employed to model the compressive strength, splitting tensile strength, and flexural strength of waste sugarcane bagasse ash (SCBA) concrete. Particle swarm optimization (PSO) algorithm was used to fine-tune the hyperparameter of the proposed MEP. The formulation of SCBA concrete was correlated with five input parameters. To train and test the proposed model, a large number of data were collected from the published literature. Afterward, waste SCBA was collected, processed, and characterized for partial replacement of cement in concrete. Concrete specimens with varying proportion of SCBA were prepared in the laboratory, and results were used for model validation. The performance of the developed models was then evaluated by statistical criteria and error assessment tests. The result shows that the performance of MEP with PSO algorithm significantly enhanced its accuracy. The essential input variables affecting the output were revealed, and the parametric analysis confirms that the models are accurate and have captured the essential properties of SCBA. Finally, the cross validation ensured the generalized capacity and robustness of the models. Hence, the adopted approach, i.e., MEP-based modeling with PSO, could be an effective tool for accurate modeling of the concrete properties, thus directly contributing to the construction sector by consuming waste and protecting the environment.

“…The small number of voids in SCBA may have been due to the uncontrolled burning and grinding of the sieved ash. However, the presence of a large number of voids indicated the greater water absorption of the mixture containing SCBA [ 28 ].…”

This research aimed at exploring the effects of a mixture of sodium hydroxide (NaOH) and potassium hydroxide (KOH) activators in a sugar cane bagasse ash (SCBA)-based geopolymer cement paste. Bagasse ash replacement was 20% of cement by weight. The mixture of NaOH and KOH comprised 4, 8, and 12 M solutions with mixing percentages of 0%, 20%, 40%, 60%, 80%, and 100% for all possible combinations. A pH test was performed on each possible combination of solutions. A Chapelle’s test, XRD, X-ray fluorescence (XRF), and SEM analysis were used to check whether the SCBA exhibited pozzolanic reactivity. Subsequently, the SCBA geopolymer cement paste was tested for compressive strength, water absorption, permeable porosity, and sorptivity. It was estimated that the geopolymer cement paste exhibited higher absorption and sorptivity values than control mixtures when molarity increased. However, the samples prepared with combinations of the 8 M activator solution exhibited consistent absorption, sorptivity, and compressive strength values when compared to the control and other geopolymer mixtures with 4 and 12 M activator solutions. Thus, the two activator solutions G8N408K60 and G8N208K80—where GxNayKb represents the geopolymer concrete sample prepared by adding solutions of two bases, i.e., ‘xNayKb’ showing an ‘a’ percentage of ‘x’ molar NaOH and a ‘b’ percentage of ‘y’ molar KOH—were obtained as the optimum molar ratio of the activator in geopolymer concrete. The geopolymer cement pastes, along with the optimum and control samples, were further tested for concrete durability, SEM, and TGA tests. The G8N208K80 sample exhibited a better mechanical and durability performance than the G8N408K60 sample. The durability performance of the geopolymer concrete was also superior to ordinary concrete. Moreover, the geopolymer concrete achieved a 21% reduction in global warming potential compared to the control mixture. Thus, it can be concluded that the use of SCBA ash in geopolymer concrete can address the ash disposal and CO2 emission problems with enhanced durability.

En el presente trabajo de investigación se empleó la ceniza de bagazo de caña de azúcar (CBCA) como sustituto parcial al cemento portland con la finalidad de mejorar las propiedades mecánicas del suelo de estudio. Se evaluaron los pesos volumétricos secos máximos, humedad optima, compactación y CBR, de un suelo tipo Subbase comparándolo con mezclas de suelo con adiciones del 3%, 5% y 7% de CPC, CBCA y combinaciones de CPC-CBCA. Todos los ensayos se realizaron de acuerdo con la normativa de la SCT para el control de materiales y ensayos mencionados. Los resultados mostraron mejoras significativas en el CBR, con sustitución de hasta 25% y hasta 50% de CBCA por CPC.
