Admixtures for cementitous compositions

A cement setting and hardening accelerator having the formula

Cement accelerators

Fluidity control of cementitious compositions

A random copolymer in free acid or salt form having the following types and numbers of monomer units; ##STR1## in which M is hydrogen or a residue of a hydrophobic polyalkylene glycol or polysiloxane,

Copolymers

A process for modifying the slump of a concrete or mortar by the addition at different times of a water-soluble poly(alkylene oxide) and a .beta.-naphthalene sulphonate-formaldehyde condensate, a plasticizer or superplasticizer which is selected from lignosulphonates, melamine sulphonate formaldehyde condensates, carboxylates and selected styrene-maleic anhydride copolymers. The poly(alkylene oxide) is preferably partially replaced by a (hydroxy)alkyl cellulose. The process is advantageously used in shotcreting.

Workable cementitious compositions

A storable cement-mortar dry mix, which comprises the components cement, aggregate, reaction resin and hardener in a single mixture, wherein the hardener is present as the reaction product of the hardener with an organic acid or a functional derivative thereof.

Production of cement-mortar dry mix

The invention relates to organic copolymers in free acid or salt form with recurring units of formula I ##STR1## in which R is an alkylene radical with 2 to 6 carbon atoms,

Chemically treated anhydride copolymers and cementitious mixtures

Cationic fixing agents based on the reaction products of

Cationic polycondensates useful for improving the fastness of dyeings on

Polymeric compounds (A) obtained by the reaction of epihalo-hydrin with a polyalkylene polyamine are useful as textile treatment agents. As pretreatment agents they improve the color yield of the subsequent dyeing, as aftertreatment agents they improve fastness properties. Certain of the products (A) are novel.

Treatment of textile materials to improve the fastness of dyeings made

Aftertreatment of textile fibres which have been optically brightened or dyed or printed with certain direct dyes, or with basic or sulphur dyes, increases wet-fastness properties. The aftertreatment agent is a polymeric, polybasic amino compound, which is applied under alkaline conditions.

The wet fastness properties of direct or reactive dyeings on cellulosic substrates are improved by aftertreatment with a precondensate of

Water-soluble precondensates useful for improving the fastness of dyes

The wet fastness properties of direct or reactive dyeings on cellulosic substrates are improved by aftertreatment with an agent comprising
