The present invention relates to ready-to-use drying joint compounds that exhibit improved performance characteristics due to the presence of a hydrophobically modified polygalactomannan.

Joint compounds

Rheology modifying admixture comprising a) from 80 to 99% w/w of hydroxyalkyl guar, cellulose ether, or mixture thereof; b) from 1 to 20% w/w of biopolymer selected from diutan gum and welan gum, and hydraulic compositions containing the rheology modifier admixture together with a superplasticizer.

Rheology modifying admixture

Disclosed are cementitious mortar additives comprising a hydroxyalkyl guar derivative having a molar substitution of from about 0.7 to about 3. Also disclosed are dry cementitious mortar compositions including from 0.1 to 1.5% by weight of the additive and cured cementitious mortars obtained by addition of water to the dry cementitious mortar compositions.

Additives based on hydroxyalkyl guar derivatives for use in mortars and mortars including them
