Can hempcrete be made from Mars or Moon aggregate instead of lime, and 4d printed?

FWIU, lime requires coral for production? Is lime sustainable?

Alternative solutions for: structural wood frame in a hempcrete structure: stacking hempcrete blocks on structural forms that are stronger and more insulting than structural concrete; green concrete, a carbon and thermal gradient sink; and Hempwood, which is apparently stronger than spec lumber of the same dimensions as well.
