A curing accelerator composition for building chemical mixtures comprises a mineral constituent and a polymeric water-soluble dispersant. The mineral constituent comprises a semi-ordered calcium silicate hydrate having an apparent crystallite size of 15 nm or less and less than 35% by weight of crystalline phases other than the semi-ordered calcium silicate hydrate. The composition displays a more pronounced accelerating effect than comparative compositions in which the mineral component comprises a calcium silicate hydrate having a higher degree of crystallinity.

The invention relates to an additive which can be used as a hardening accelerator for hydraulically setting compositions, comprising a) at least one polymeric dispersant comprising structural units having anionic or anionogenic groups and structural units having polyether side chains, b) at least one sulfonic acid compound of the formula (I) ##STR00001##
in which A.sup.1 is NH.sub.2, NHMe, NMe.sub.2, N(CH.sub.2—CH.sub.2—OH).sub.2, CH.sub.3, C.sub.2H.sub.5, CH.sub.2—CH.sub.2—OH, phenyl, or p-CH.sub.3-phenyl and K.sup.n+ is an alkali metal cation, or one equivalent of a cation selected from Ca.sup.2+, Mg.sup.2+, Sr.sup.2+, Ba.sup.2+, Zn.sup.2+, Fe.sup.2+, Fe.sup.3+, Al.sup.3+, Mn.sup.2+, or Cu.sup.2+, and c) calcium silicate hydrate particles.

The present invention relates to a construction chemical composition comprising Portland cement, a water retention agent, a dispersing agent, and a hardening accelerator comprising calcium-silicate-hydrate, as well as a mortar composition containing said construction chemical composition. Although the composition is based on Portland cement it has a pull-off strength after 6 h meeting the DIN requirements and can therefore be used as a fast setting tile mortar.
