Analysis on Thermal Behavior of Bamboo Leaf Ash-Blended Cement Paste

This is an attempt to explore the impact of bamboo leaf ash (BLA) substitution on the thermal properties of concrete. To identify and determine the chemical makeup of a substance, infrared spectroscopy was used to investigate the interaction of matter and electromagnetic radiation. The current study employs Fourier transform infrared spectroscopy to estimate the amount of heat damage in hydrated Portland cements containing bamboo leaf ash (BLA). The hydrated specimens of BLA-mixed cement paste were treated at temperatures ranging from 27 to 1000°C with a 20°C gap between the higher next values. To explore the thermal properties of bamboo leaf ash (BLA)-blended concrete paste, thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR) investigations were performed after the bamboo leaf ash and cement were combined at each level of suitable replacement. The TGA research demonstrated that the BLA substitutions of 5% and 10% were more thermally stable than the control mix. At the same time, FTIR research indicated that the concentration of calcium hydroxide (Ca(OH)2) declines during the combination, enhancing the development of the calcium silicate hydrate gel (C-S-H) bond. The mass loss and heat flow graphs obtained by TGA are in good agreement with the phase changes seen in the specimens using FTIR. As a consequence, it is possible to declare that FTIR analysis is a technically viable test technique for forecasting concrete feature deterioration under the impact of high temperatures. According to the current study, Ethiopian lowland bamboo leaf ash has significant pozzolanic properties and increases concrete thermal resistance.
