Resistencia al fuego y propiedades físicas y mecánicas de adobes con 5% de ceniza de bagazo de caña según su granulometría

Abstract

Abstract: This study evaluated the influence of sugarcane bagasse ash (SCBA) particle size, incorporated at 5% by volume, on the behavior of adobe made with a clayey–sandy soil, considering mechanical, physical, thermal, acoustic, and post fire compressive properties. Five series of specimens were produced (control without SCBA and four mixtures with SCBA sieved at #100, #200, pan, and a combined gradation), manufactured by dry mixing and cured for 28–30 days, then tested for thermal transfer, sound insulation, flexural and compressive strength, capillary absorption, immersion degradation, and post fire compression. Results showed that the finer SCBA (#100) increased compressive strength and improved sound attenuation, whereas the control adobe retained the highest flexural strength; the #200 gradation reduced heat flux through the material, and all SCBA mixtures were more susceptible to water than the control. After fire exposure, the combined gradation mix reached the highest compressive strength and strain. It was concluded that no single optimal SCBA.
