Abstract (en)
[origin: EP3670467A1] The invention concerns a carbonatable clinker material comprising at least 60 wt.% of amorphous phase, advantageously at least 80 wt.% of amorphous phase, more advantageously at least 99 wt.% of amorphous phase, more advantageously 100 wt.% of amorphous phase, compared to the total weight of the carbonatable clinker material, wherein said material has the following oxide composition:- calcium oxide, magnesium oxide, sodium oxide, potassium oxide and silicon dioxide are present in molar amounts such that (CaO + MgO + Na<sub>2</sub>O + K<sub>2</sub>O)/SiO<sub>2</sub>ranges between 0.7 and 1.8, preferentially from 0.9 to 1.6;- total soluble alkali ranges between 0.01 and 0.06 wt.% of the amount of carbonatable clinker material.
