The aim of this research was to evaluate the potential for using cellulose microfiber combined with crystalline microcellulose to produce cementitious slabs. Cementitious slabs were prepared with the combined addition of MFC-MCC cellulose. The specimens were pressed and their physical and mechanical properties were evaluated after 28 days. The results indicated that swelling in thickness was not affected by the combined addition of MFC-MCC cellulose, promoting dimensional stability. The modulus of rupture results indicated that the combined MFC 0.5-MCC 0.6 formulation showed a significant improvement when compared to the reference cementitious slabs. The results for swelling in thickness and modulus of elasticity of the cement boards with combined MFC-MCC addition meet the minimum requirements of the standard for commercial wood-cement boards.
