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

   
   

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.

Sono rilevati gli additivi cementizi del mortaio che contengono un derivato idrossialchilico del guar che ha una sostituzione molare di circa 0.7 a circa 3. Inoltre sono rilevate le composizioni cementizie asciutte nel mortaio che includono 0.1 - 1.5% del peso dell'additivo ed i mortai cementizi curati ottenuti tramite l'aggiunta di acqua alle composizioni cementizie asciutte nel mortaio.
