摘要
A mortar comprising an inorganic binder such as anhydrite, gypsum or cement is rendered more flowable and processible by incorporating therein a condensation product of formaldehyde with a sulfonated aromatic ether, imine or sulfone, e.g. preferably about 0.3 to 2% by weight of the binder of the condensation product of formaldehyde with sulfonated ditolyl ether. There may also be present an auxiliary such as FeSO4 . 7 H2O, Al2(SO4)3. 18 H2O or KA1(SO4)2, as well as an additive such as a plasticizer, hardening accelerator, retarder, air-entraining agent, thickener, activator or anti-foam agent, and/or an aggregate such as sand, gravel, perlite, pumice or foamed plastic beads.
