A hydraulic mortar, comprising:
- 70% to 95% cullet including milled soda-lime glass, at least a first portion of the milled soda-lime glass being extra-fine glass having a particle size under one micron, the extra-fine glass being 4%-30% by weight of the hydraulic mortar;
- and
- cementitious material including Portland clinker having a particle size of 0.1 microns to 30 microns.
A method of preparing hydraulic mortar, comprising:
- providing a quantity of cullet at 70% to 95% by weight of the hydraulic mortar, the quantity of cullet including milled soda-lime glass;
