1. A method of reducing CO2 in cement production, comprising the steps of:
forming a cementitious reagent, wherein the cementitious reagent (i) is a non-crystalline solid, (ii) is in the form of a powder, (iii) has a particle distribution with D[3,2] of 20 μm or less, and has less than about 10 wt. % CaO; and
adding the cementitious reagent to a binder.
