Claims20
A cementitious solid comprising:
- a binder including magnesium;
- a catalyst, wherein the catalyst is at least one of alkali metal carbonate, alkali metal bicarbonate, or alkali metal borate;
- and
- biomass,
- wherein composition of the cementitious solid comprises 40 wt % to 75 wt % binder, 20 wt % to 57 wt % biomass, and 3 wt % to 10 wt % catalyst based on the total weight percentage of the binder, the catalyst, and the biomass.

A mixture for use with water to form a slurry, comprising:
- a binder including magnesium;
- a catalyst, wherein the catalyst is at least one of alkali metal carbonate, alkali metal bicarbonate, or alkali metal borate;
- biochar;
- and
- additional biomass,
- wherein composition of the cementitious solid comprises 30 wt % to 60 wt % binder, 5 wt % to 15 wt % additional biomass, and 3 wt % to 7 wt % catalyst, and 30 wt % to 60 wt % biochar based on the total weight percentage of the binder, the catalyst, the additional biomass, and the biochar.
