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

Abstract

Abstract: This study investigates the effect of sugarcane bagasse ash (CBCA) pretreated with acetic acid on the physical and mechanical properties of cement mortars, focusing on compressive strength, heat transfer, water absorption, fire resistance, and airborne noise. These properties were evaluated by comparing treated and untreated samples. The results show that the ash, when pretreated before calcination, improves compressive strength, although it does not match the strength of the control samples. In addition, water absorption is considerably lower and acoustic insulation is better because of the fine particles in the ash. In contrast, fire resistance in the CBCA samples significantly reduced the structural integrity. It is concluded that the use of sugarcane bagasse ash in mortars is feasible but requires precise control of dosage and treatment to optimize its properties.
