Albizia plurijuga, baño caliente-frío, Fraxinus americana, Spathodea campanulata.Resumen
El objetivo de la investigación fue determinar las densidades y los módulos dinámicos con vibraciones longitudinales, antes y después de impregnar con sales de boro las maderas de Spathodea campanulata, Fraxinus americana y Albizia plurijuga. Para cada especie se prepararon 40 probetas, se impregnaron con el método de baño caliente-frío y se determinaron las retenciones correspondientes a concentraciones de 1 %, 2 % y 3 %. Las densidades de las maderas no se modifican después del tratamiento. Los módulos dinámicos de F. americana y A. plurijuga no variaron por el tratamiento. Caso diferente es S. campanulata cuyos módulos dinámicos sí variaron.
