  • Comparison of original and washed pure sugar Cane Bagasse ashes as supplementary cementing materials
    Construction and Building Materials, 2021
    Co-Authors: Gabriela Pitolli Lyra, María Victoria Borrachero, Lourdes Soriano, Jordi Payá, João Adriano Rossignolo
    Abstract:

    Abstract The objective of this study was to evaluate the effects of potassium extraction on the pozzolanicity of sugar Cane Bagasse ash (SCBA), with the aim of producing reactive ash for use in cementitious composites. The sugar Cane Bagasse ashes were produced at 600 °C for 60 min, with a heating rate of 4 °C/min. The ashes were then ground and washed for potassium extraction. In order to assess the ash behaviour before and after potassium extraction, the following procedures were performed: energy-dispersive spectroscopy (EDS), loss on ignition (LOI), particle size distribution, x-ray powder diffraction (XRD), x-ray diffraction in calcium hydroxide paste, analysis of lime fixation by thermogravimetry, and evaluation of pozzolanic reactivity analyses. Results show that the extraction of potassium, increases the concentration of silica causing a greater pozzolanic reactivity of the ashes.

  • Use of slag/sugar Cane Bagasse ash (SCBA) blends in the production of alkali-activated materials
    Materials (Basel Switzerland), 2013
    Co-Authors: Vinicius N. Castaldelli, J.m. Monzo, María Victoria Borrachero, Lourdes Soriano, Jorge Luís Akasaki, José Luiz Pinheiro Melges, Mauro Mitsuuchi Tashima, Jordi Payá
    Abstract:

    Blast furnace slag (BFS)/sugar Cane Bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar Cane industry were poured. After previous dry and grinding processes, SCBA was chemically characterized: it had a large percentage of organic matter (ca. 25%). Solutions of sodium hydroxide and sodium silicate were used as activating reagents. Different BFS/SCBA mixtures were studied, replacing part of the BFS by SCBA from 0 to 40% by weight. The mechanical strength of mortar was measured, obtaining values about 60 MPa of compressive strength for BFS/SCBA systems after 270 days of curing at 20 °C. Also, microstructural properties were assessed by means of SEM, TGA, XRD, pH, electrical conductivity, FTIR spectroscopy and MIP. Results showed a good stability of matrices developed by means of alkali-activation. It was demonstrated that sugar Cane Bagasse ash is an interesting source for preparing alkali-activated binders.

  • sugar Cane Bagasse ash scba studies on its properties for reusing in concrete production
    Journal of Chemical Technology & Biotechnology, 2002
    Co-Authors: Jorge Paya, L Diazpinzon, J.m. Monzo, María Victoria Borrachero, L M Ordonez
    Abstract:

    Sugar Cane Bagasse is an industrial waste which is used worldwide as fuel in the same sugar-Cane industry. The combustion yields ashes containing high amounts of unburned matter, silicon and aluminium oxides as main components. These sugar-Cane Bagasse ashes (SCBA) have been chemically, physically and mineralogically characterized, in order to evaluate the possibility of their use as a cement-replacing material in the concrete industry. Determination of parameters such as carbon content (by thermal analysis methods), presence of crystalline material (by X-ray diffractometry), granulometric distribution (by laser diffraction in water suspensions), morphology of particles (by scanning electron microscopy) and reactivity towards lime (pozzolanic activity by thermogravimetric monitoring in lime/SCBA and cement/SCBA pastes) have been carried out.
