Glutinous rice mortar: the wisdom of ancient architects

About 1500 years ago, ancient architects in China skillfully used glutinous rice mortar to build city walls. Glutinous rice contains 100% amylopectin, which is not easy to break and forms a hard structure when mixed with lime.

♂? Complexity of traditional technology

The traditional glutinous rice mortar gradually withdrew from the construction market because of its complex technology and slow curing speed. Now glutinous rice mortar is mainly used for the restoration of ancient buildings.

The first choice for the restoration of ancient buildings

There are many problems exposed by cement in the restoration of ancient buildings, such as salt precipitation, short service life and disharmony with ancient buildings. Therefore, many ancient buildings still choose glutinous rice mortar for repair.

The cost is higher

From the cost point of view, glutinous rice mortar is indeed much more expensive than ordinary cement mortar. At present, glutinous rice mortar is mainly used for the restoration of ancient buildings, not high-rise buildings.
