With the continuous development of the construction industry, the performance requirements of mortar are increasing day by day. How to improve the workability, adhesion and durability of mortar has become an urgent problem that major building materials manufacturers need to solve. Recently, mortar products using hydroxypropyl methylcellulose (HPMC) have gradually emerged in major projects, showing their excellent performance and wide application prospects.

In contrast, starch consists largely of α-D-glucose units, connected through α(1→4) glycosidic bonds in its linear form (amylose), and through α(1→6) bonds at branch points in its branched form (amylopectin). The branched structure of amylopectin and the helical conformation of amylose are conducive to storing energy. Starch is soluble in water and can form a gel-like consistency when heated in water, which aids in its role as an energy reserve in plants, particularly in tubers and seeds.
