    Abstract: An emulsifier composition comprising (a) a non-ionic emulsifier having an HLB-value of about 10 to 20 and (b) a polyoxyalkylene-polyester of which about 5 to 50% by weight comprises polyoxyalkylene radicals. It may be used in admixture with phosphoric acid esters, serving to reduce foaming and prevent settling of aqueous suspensions such as cement and calcium sulfate slurries.

    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 FeSO4,7 H2O,Al2(SO4)3.18 H2O or KAl(SO4)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.

    Abstract: In the production of a floor topping by the flow method, comprising providing a water-absorbing layer on a floor to be topped, pouring a free-flowing mass comprising an inorganic binder and water onto said water-absorbing layer whereby said mass forms a level floor topping, and allowing said mass to harden, the improvement which comprises employing as said water-absorbing layer a strong porous open-cell material. The open-cell material which serves as a water absorptive underlay preferably comprises at least one of anhydrite, gypsum, cement and lime. Preferably it is formed in place by casting a foamed mass comprising an aqueous suspension of gypsum, an aluminum salt, hydrogen peroxide and a manganese compound.
