“…As in earlier works, the reasons for the development of compressive strength in BA mortar and the increase in compressive strength up to the 15% cement replacement of BA may be due to the silica content, fineness, specific surface area, degree of reactivity of BA and pozzolanic reaction between calcium hydroxide and reactive silica in BA. Additionally, the degree of reactivity of BA plays some part in the process of developing compressive strength [7,10,18,[47][48][49][50][51]. According to the findings, an increase in compressive strength may be attributed to the packing effect of BA due to particle fineness, the quantity of the cement replacement and the age of the mortar.…”

Utilization of Sugar Mill Waste Ash as Pozzolanic Material in Structural Mortar

et al. 2023

Bagasse is produced as a waste in the sugar production process, which is used as fuel to stoke boilers in the sugar mills. The concluding product of this burning is residual sugarcane bagasse ash (BA), which is normally dumped or used as low-quality fertilizer. The ash for this study was collected from a reputed sugar mill located in the northern region of Bangladesh. Type I Portland cement (PC) was partially replaced with that finely ground bagasse ash without any pretreatment. The ground BA was used as a replacement for Portland cement at 5, 10, 15, 20, 25 and 30% of BA, respectively, in structural mortar. In addition, chemical characterization, specific gravity, X-ray diffraction (XRD), scanning electron microscopy (SEM), setting time, a strength activity index, compressive strength, water absorption, density and durability in a chloride environment of mortar were determined. The strength activity index result indicates that the used BA has the pozzolanic properties to be used as a partial cement replacement. The results showed that, at the age of 56 days, the mortar samples containing 5–15% ground bagasse ash had higher compressive strengths than the control mixture (mortar without ground bagasse ash). Mortar containing 15% ground bagasse ash had the highest mechanical and durability properties. Therefore, the substitution of 15% BA is acceptable for producing good quality structural mortar in the civil engineering construction field except in chloride environments.

“…El bagazo de la caña de azúcar ha sido investigado, tanto como materia prima o como material puzolánico, para su uso en la manufactura de cementos comerciales y otros compuestos (4)(5)(6). La utilización como puzolana de los desechos de la agricultura requiere calcinación previa, pero la actividad puzolánica varía sustancialmente como resultado de las condiciones de calcinación y la naturaleza de los materiales de origen.…”

“…Es así, que existen resultados contradictorios acerca de la efectividad puzolánica de la ceniza del bagazo de caña de azúcar (Sugar Cane Bagasse Ash, SCBA) que se atribuyen al empleo de diferentes temperaturas de calcinación (7)(8)(9). En cuanto a la ceniza de la hoja de caña de azúcar (Sugar Cane Straw Ash, SCSA), tanto obtenida a partir de hojas calcinadas a cielo abierto en las vecindades de una fábrica de azúcar (5-7) como en hornos rudimentarios (5,6,10), similares a los incineradores construidos en Asia para producir ceniza de cascarilla de arroz, se obtiene una significativa presencia de material amorfo (vítreo) y alta actividad puzolánica. Algunos investigadores han desarrollado modelos matemáticos para describir el proceso, tanto en el régimen cinético como en el cinético-difusivo, permitiendo determinar los parámetros que caracterizan el proceso y la cinética de la reacción puzolánica (11)(12)(13)(14).…”

“…As a result, the findings on sugar cane bagasse ash (SCBA) pozzolanicity are contradictory, a situation attributed to the use of different incineration temperatures (7)(8)(9). The sugar cane straw ash (SCSA) obtained by burning the material either in the open air in the proximity of a sugar mill (5-7) or in rudimentary kilns (5,6,10) similar to the incinerators built in Asia to produce rice husk ash contains significant proportions of amorphous (vitreous) material and exhibits high pozzolanicity. A number of researchers have developed mathematical models to describe the kinetic and kineticdiffusive processes involved, from which they have determined the parameters that characterise the pozzolanic reaction and its kinetics (11)(12)(13)(14).…”

“…In Sugar cane bagasse has been researched both as a prime material and as a pozzolan in the manufacture of commercial cements and other compounds (4)(5)(6). The use of agricultural waste as a pozzolan entails incineration, but pozzolanicity varies substantially depending on the incineration conditions and the nature of the source materials.…”

RESUMENEn el siguiente artículo se presenta una evaluación de la hoja de caña de azúcar calcinada bajo condiciones controladas en aras a obtener ceniza reactiva (con propiedades puzolánicas). La ceniza fue analizada mediante las técnicas de difracción de rayos X, fluorescencia de rayos X y microscopía electrónica de barrido. Los resultados del estudio mostraron que la ceniza de hoja de caña de azúcar sí contiene una significante presencia de material amorfo y un alto porcentaje de sílice (81,0%). Se valoró la aptitud de las cenizas obtenidas como puzolana mediante métodos químicos, como el ensayo de Frattini y métodos mecánicos, como el índice de actividad puzolánica. Como modelo a seguir para la interpretación de la puzolanicidad de la ceniza de hoja de caña se utilizó el método de Feret. Se concluye que la ceniza de hoja de caña sí es apta para ser utilizada como adición puzolánica.Palabras claves: puzolana, cemento Portland, material amorfo, hidróxido de calcio, mortero. ABSTRACTThis paper presents the results of the evaluation of the sugarcane leaf, burnt under controlled conditions in order to obtain a reactive ash with pozzolanic properties. Chemical analysis, amorphousity and surface structure of the sugar cane straw ash (SCSA) were studied by X-ray diffraction, X-ray fluorescence spectroscopy and scanning electron microscope (SEM). The results of this research showed that SCSA has significant presence of amorphous material and a high content of silica (81.0%). The pozzolanic activity of the SCSA was evaluated by the Fratini test and the pozzolanic activity index. In order to interpretate the pozzolan activity, the Feret method was used. It is conclude that the SCSA presents pozzolanic characteristics for blending Portland cement.
