Abstract

The invention relates to a setting and hardening accelerator of hydraulic binders, which accelerator comprises the following proportions by mass: - from 25 to 35 percent of one at least sulfo-aluminous clinker, - from 45 to 55 percent of one at least sulfates source with water solubility greater than 4g.L-1 at 20 deggrees Celsius and - from 10 to 20 percent of one at least sulfates source with water solubility lesser than 4g.L-1 at 20 degrees Celsius, where the clinker in question contains mineral solutions of the calcium aluminates type. The cement composition containing said setting accelerator can be performed in temperatures ranging form 5 to 35 degrees Celsius and used for obtaining a shotcrete or a sealing or wedging mortar exhibiting enhanced mechanical resistance to compression.
