jismart2024078: Study on Biomass Fly Ash Difference During Modification and Effects of Curing Temperature on Compressive Strength

Abstract

Curing temperature plays a crucial role in determining the compressive strength of cement slurry systems by influencing the pozzolanic reaction, a key process in cement hydration. However, varying processes, climatic conditions, and weather can result in different initial curing temperatures, making the relationship between curing temperature and compressive strength an underexplored area. Biomass fly ashes, derived from the combustion of organic materials, exhibit diverse physical properties, chemical composition, depending on the raw materials and combustion methods used. This study investigates the effect of curing temperature on cement-based composites incorporating different types of biomasses fly ash. All fly ash samples were modified using the same flotation technique to enhance their performance as cement substitutes. By analyzing the activity index and compressive strength of the composites at various curing temperatures, the research aims to provide insights into the behavior of biomass fly ash in cementitious systems under different environmental conditions. Flotation enhances biomass fly ash performance, with higher curing temperatures (e.g., 35°C) accelerating pozzolanic reactions and compressive strength, while lower temperatures slow this effect, especially in biomass fly ashes.
