Abstract

An alkali-free accelerator for use with spray-applied cementitious compositions such as concrete and mortar is the reaction product in aqueous medium of amorphous aluminium hydroxide, aluminium sulphate, formic acid and phosphoric acid. These accelerators performs as well as known alkali-free accelerators and are exceptionally stable, even in hot conditions.
