Abstract: Cement composite boards comprising cellulose filaments (CF) and/or CF-containing pulp, are described. The composite boards have at least an improved modulus of rupture when compared with similar board that are free of CF. Methods for producing the CF and/or CF-containing pulp reinforced cement boards are also described. The CF cement composite board comprises: cellulose filaments (CF) and/or CF-containing pulp, and cement, wherein the CF has an aspect ratio of 200 to 5000, comprising a weight % of CF is from 1% to 20% by weight of the composite board. The composite boards herein described may have a modulus of rupture of more than 7 MPa.

Abstract: The present provides a concrete and mortar mix and composition thereof with poor quality sand such as desert sand, hydraulic binder (cement) and filamentous cellulose, where the desert sand/spherical sand replaces conventional concrete river sands. The present disclosure also relates a filamentous cellulose, such as, cellulose nano filaments (CF), cellulose nano filaments, cellulose nanofibrils (CNF) and microfibrillated cellulose (MFC) as a concrete/mortar and sand adhesion additive with hydraulic binder (cement), and to a method of making the concrete. This method also relates to a method to prevent the sliding of individual sand grains against one another and therefor similarly contributes to the stabilization of the building materials.
