DESERT SAND AND FILAMENTOUS CELLULOSE IN CONCRETE AND MORTAR

摘要

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.
