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.

most lime comes from limestone, extracted by quarries/mines- although sometimes it is sourced from coral

the process of producing lime can involve a number of not-very-sustainable steps, hopefully which can be substituted for more environmentally responsible alternatives
