Abstract (en)
[origin: WO2019180191A1] The invention relates to an aqueous suspension comprising 5 to 65 wt.% of calcium hydroxide, wherein at least 50 wt.% of the calcium hydroxide is present in the form of nanoparticles, and at least one compound for stabilizing the suspension. The aqueous suspension accelerates the setting of mineral binder compositions without adversely affecting the processing properties of the composition.
