ASTM WK97653

New Test Method for Workgroup to identify mineral binders for hemp based construction materials.

1. Scope

To identify the materials and performance required for mineral based
binders to be mixed with hemp hurd and other hemp based products to
produce construction materials.

Keywords

Lime; Cement; Biocomposite; Hemp-Lime; Hempcrete

Rationale

Binders are necessary to create hemp based construction materials.
The most common hemp based building product is Hempcrete or Hemp-lime,
which utilize mineral based binders such as lime and cement.
Standards are needed to establish acceptable raw mineral ingredients,
proportions and performance requirements for these binders to ensure
material safety and consistency.
