Abstract

MANSANEIRA, Emerson Carlos; SCHWANTES-CEZARIO, Nicole; BARRETO-SANDOVAL, Gersson Fernando  and  MARTINS-TORALLES, Berenice. Sugar cane bagasse ash as a pozzolanic material. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.201, pp.163-171. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n201.61409.

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. 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.

Keywords : Sugar cane bagasse ash; pozzolanic activity; mechanical performance.
