ABSTRACT:
A mortar comprising an inorganic binder such as anhydrite, gypsum or cement is rendered more flowable and processible by incorporating therein a sulfonic acid group-containing formaldehyde condensation product with a cycloalkanone, e.g. preferably about 0.05 to 5% by weight of the binder of the condensation product of sodium sulfite, formaldehyde and cyclohexanone. There may also be present an auxiliary such as FeSO.sub.4,7 H.sub.2 O,Al.sub.2 (SO.sub.4).sub.3.18 H.sub.2 O or KAl(SO.sub.4).sub.2, as well as an additive such as a plasticizer, hardening accelerator, retarder, air-entraining agent, thickener, activator, anti-foam agent or synthetic resin dispersion, and/or an aggregate such as sand, silica, perlite, pumice or foamed plastic beads.
