Cement is the most used construction material, being widely applied in civil construction. Although the cement-based materials have excellent resistance to compression, they have some limitations and problems, such as low tensile strength and deformation capacity and cracking problems.
Cellulosic-based fibers, namely sisal fibers, can be used to minimize these problems. Sisal fibers have excellent mechanical properties, non-toxicity, low cost and are highly available, with Brazil being its main world producer. On the other hand, the use of nano / micro materials for the manufacture of high performance composites is generating enormous interest in many sectors.
Microcrystalline cellulose (MCC) has excellent mechanical properties and high crystallinity.
However, the direct addition of MCC to the cementitious composite presents problems of agglomeration. In this context, the present work has as main purpose the development and characterization of cementitious composites reinforced to multiscale, with the addition of microcrystalline cellulose (MCC) and sisal fibers, looking for a synergistic effect, taking an innovative approach in this domain, with the study mechanical behavior, microstructure and durability after aging in a climatic chamber.
