Abstract

A setting and hardening accelerator (I) is claimed, contg.: (a) calcium sulphate dihydrate; and (b) amorphous Al hydroxide and/or an amorphous and/or crystalline basic Al salt. Also claimed is a process for accelerating the setting and hardening of cement, or cement-based mortar or concrete, by adding 0.1-20 wt% (I) (w.r.t. cement) to a cement-contg. mixt.
