Fermented from rice, rice-koji (the mold used to convert the starch in rice into fermentable sugars), and water, and then pressed through a mesh (to strain away the solids and yield a clear beverage).

A modification to the existing hardening function is proposed to reduce the mesh sensitivity of the plastic strain at peak stress.

In the experiment the strain of concrete, steel bar, steel mesh, composite mortar and the ultimate load carrying capacity are tested.
