Evaluation of the physical and mechanical properties of cementitious boards with combined addition of cellulose microfiber and crystalline microcellulose

This study aims to evaluate the potential of cellulose microfiber (FC) combined with crystalline microcellulose (MCC) to produce cementitious boards. Specimens were fabricated by pressing, and their physical and mechanical properties were evaluated after 28 days. The rupture modulus and elasticity results indicated that the combined formulation FC 0.5-MCC 0.6 significantly improved compared to reference cementitious boards. The swelling thickness and elasticity modulus results of all cementitious boards produced with the addition of cellulose microfiber and crystalline microcellulose meet the standard's minimum requirements for cementitious boards, proving to be an exciting alternative for new technologies in fiber cement.
