Sugar cane bagasse ash as a pozzolanic material

This study aimed to verify the SCBA's potential use as a partial replacement of Portland cement. Therefore, the experiment was divided in two stages; in the first, mineralogical and chemical analyses were performed with two samples of ash, in-natura and calcined at a temperature of 600°C for 6h...

Therefore, the experiment was divided in two stages; in the first, mineralogical and chemical analyses were performed with two samples of ash, in-natura and calcined at a temperature of 600°C for 6h. After these analyzes, it was observed that the calcined ash presented a greater tendency of material in the amorphous state, which possibly made the material the most reactive. For this reason, only the calcined ash was ground for 1 and 2h. These samples were further studied in order to check the pozzolanic activity index and the compressive strength, evaluating the replacement of 10, 20 and 30% Portland cement by ground SCBA. The results showed an increase in the pozzolanic activity index only in samples of calcined and ground SCBA, showing that calcined ash must undergo a grinding process to present pozzolanic activity.Este estudio tiene como objetivo verificar el potencial de uso del CBCA como sustitución parcial del cemento Portland. Por lo tanto, la campaña experimental fue dividida dos etapas; En la primera, se realizaron análisis mineralógicos y químicos con dos muestras de ceniza, crudas y calcinadas a una temperatura de 600°C durante 6h. En la segunda etapa, se observó que las cenizas calcinadas presentaban una mayor cantidad de material en estado amorfo, lo que posiblemente hizo que el material fuera el más reactivo. Por esta razón, sólo la ceniza calcinada se molió durante 1 y 2h. Adicionalmente estas muestras fueron estudiadas para verificar el índice de actividad puzolánica y la resistencia a la compresión, evaluando la sustitución de cemento Portland en proporciones de 10, 20 y 30% por SCBA. Los resultados mostraron un incremento demostrado que tanto la ceniza in-natura como la ceniza calcinada deben ser sometidas a un proceso de molienda para presentar actividad puzolánica.Universidad Nacional de Colombia (Sede Medellín).
