Claims20
A composition comprising:
- a binder comprising a cementitious material and limestone, wherein the binder comprises at least 15% limestone by weight of the binder, and
- a plurality of cellulose nanofibers (CNFs),
- wherein the composition comprises about 0.01% to about 1% CNFs by weight relative to the binder.
A method of making a structure, the method comprising the steps of:
- extruding a mortar through an extruder to provide an extrudate,
- wherein the mortar comprises:
- a binder comprising a cementitious material and limestone,
- a plurality of cellulose nanofibers (CNFs),
- sand, and
- water;
- and
- depositing the extrudate onto a surface to provide the structure.
