1. A method for producing a lime-based cement extender composition, comprising:
milling, via a mill, feed components comprising lime particles, limestone particles, and pozzolan particles to produce a milled blend, wherein the milled blend comprises (i) at least 10% by weight of the lime particles, (ii) at least 30% by weight of the limestone particles, and (iii) at least 30% by weight of the pozzolan particles; and
separating oversized particles from the milled blend to produce a lime-based cement extender product such that 90% of the particles of the lime-based cement extender product pass 200 mesh.
