“…With the cellulose from these two residues, the SE of the straw cellulose stands out, with an absorption of 116.0 %, while that derived from the husk was 26.1 %, and although both could be used as absorbent materials, the cellulose derived from straw presented an extraordinary capacity for water absorption. This difference can be attributed to the intertwined cellulose fibers: in the straw with linear fibers, liquid can easily penetrate, separate, and lodge in the physically connected chains, while in the husk with interlocking and more united shell structures, the entry of liquid is more complex [ 60 ].…”

“…During the process of hornification, the fibers suffer changes that are directly related to their structure. In the outer cell wall occurs collapsing and hardening, which prevents the complete wetting of the fiber, which means reduction in the water absorption capacity and swelling of the fiber (68,69).…”

The present review shows the state-of-art on the approachs about improving the processing, physical-mechanical performance and durability of non-conventional fiber-cement composites. The objective of this review is to show some of these strategies to mitigate the degradation of the vegetable fibers used as reinforcement in cost-effective and non-conventional fiber-cement and, consequently, to improve their mechanical and durability properties for applications in the housing construction. Beyond the introduction about vegetable fibers, the content of this review is divided in the following sections: (i) surface modification of the fibers; (ii) improving fiber-to-cement interface; (iii) natural pozzolans; (iv) accelerated carbonation; (v) applications of nanoscience; and (vi) principles of functionally graded materials and extrusion process were briefly discussed with focus on future research needs. RESUMEN: Compuestos cementantes no convencionales reforzados con fibras vegetales: Una revisión de estrategias para mejorar la durabilidad.La presente revisión explora la actualidad en el campo de los compuestos de fibrocemento no convencionales en relación a mejoras en el proceso productivo, el rendimiento físico-mecánico y la durabilidad. El objetivo de esta revisión es exponer algunas estrategias para mitigar la degradación de las fibras vegetales utilizadas como refuerzo en fibrocementos no convencionales y rentables, obteniendo en consecuencia una mejoría en el rendimiento de sus propiedades mecánicas y durabilidad para su aplicación en el área de la construcción de viviendas. Además de la introducción en relación a las fibras vegetales, el contenido de esta revisión se divide en las siguientes secciones: (i) modificación de la superficie de las fibras; (ii) mejoramiento de la interfaz fibra-cemento; (iii) puzolanas naturales; (iv) carbonatación acelerada; (v) aplicaciones de la nanociencia; y (vi) principios de los materiales funcionalmente graduados y el proceso de extrusión fueron discutidos brevemente con un enfoque a investigaciones futuras.

Abstract-In the fibrocement industry of tiles and sheets, various kinds of natural fibers are used as reinforcement to improve the properties of the products. Although the use of fibrocement material presents a great potential due to the low cost and the high availability of vegetable fibers, several investigations have showed a behavior of low durability and rapid deterioration of the cellulosic material in an alkaline medium. With the purpose of contributing to this knowledge, the present study evaluated bleached and unbleached cellulosic pulp of eucalyptus before and after the thermal treatment consisting of 4 cycles of drying and rewetting denominated hornification. Analysis by scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed. SEM images indicated morphological changes on the surface of treated bleached and unbleached eucalyptus cellulosic pulps. Based on XRDresults, the treatment hornification did not cause the deterioration of crystalline cellulose of the fibers.
