Efecto de las cenizas de bagazo de caña de azúcar derivadas de desechos agrícolas pretratadas con agua en la resistencia al fuego, propiedades de transferencia de calor y ruido aéreo de morteros de cement

Abstract

Abstract: This study explored the impact of water pretreatment of sugarcane bagasse ash on the properties of cement mortars, including compressive strength, water absorption, density, heat and noise transfer, and fire resistance. Mortar samples with pretreated and untreated ash, classified by particle size, were compared against a control mortar. The results suggest that water pretreatment of ash improves the physical properties of mortars, although to a lesser extent, but does not show mechanical improvements such as compressive strength. Heat transfer and noise tests highlighted the better performance of samples with pretreated ash. In conclusion, water pretreatment of sugarcane bagasse ash could be a promising strategy to improve certain mortar properties, especially in compressive strength and thermoacoustic insulation. However, further research is needed to optimize this process and evaluate its long-term impact.
