A binding or setting accelerator (A) contains a combination of at least one nitrate and/or sulphite, at least one alkanolamine, at least one thiocyanate and at least one carboxylic acid. Also claimed are (i) the process for accelerating the binding or setting a hydraulic binder present in pure form or as a mixt. with latent hydraulic binders, or of mortar or concrete, contg. 0.2-5.0 wt.% (A), (ii) the use of (A) as additives to hydraulic binders or mixts. contg. the same, and (iii) hydraulic binder pre-mixts. contg. the binder and (A).
