Desert sand and filamentous cellulose in concrete and mortar

摘要

The present invention provides a concrete and mortar mix and composition thereof with lower grade sand such as desert sand, hydraulic binder (cement) and filamentous cellulose, wherein desert sand/spherical sand replaces conventional concrete river sand. . The present disclosure also provides sand adhesion additives with hydraulic binders (cement) and filamentous cellulose as concrete/mortar, such as cellulose filaments (CF), cellulose nanofilaments, cellulose nanofibrils (CNF) and fibrous cellulose (MFC). ), and a method of manufacturing concrete. This method also relates to a method that prevents the sliding of individual sand grains against each other and thus similarly contributes to the stabilization of the building material.
