Abstract

Inventia se refera la o compozitie aditiva destinata asigurarii mortarelor proprietati în stare proaspata (lucrabilitate la aplicare, segregare redusa, similare cu cele ale mortarelor cu var). în stare întarita proprietatile fizico-mecanice ale mortarelor cu aditivi sînt superioare celor cu var. Aditivul este alcatuit din 0,8...5,0 parti în greutate nonilfenoletoxilat cu 8...40 mol oxid de etilena, 1,5...6,0 parti în greutate hidroxiletilceluloza cu o viscozitate de 15...150 cP la o concentratie de 2% si 20...50 parti apa. Aditivul se introduce într-o cantitate de 2,0...6,5 dm3/l m3 mortar proaspat, în functie de destinatia mortarului (zidarie sau tencuieli) si de marca sa.The invention relates to an additive composition intended to provide fresh mortars (application workability, reduced segregation, similar to lime mortar). in the reinforced state the physico-mechanical properties of additives mortars are superior to those with lime. The additive consists of 0.8 ... 5.0 parts by weight of nonylphenoletoxylated with 8 ... 40 moles of ethylene oxide, 1.5 ... 6.0 parts by weight of hydroxyethyl cellulose with a viscosity of 15 ... 150 cP at a concentration of 2% and 20 ... 50 parts water. The additive is added in an amount of 2.0 ... 6.5 dm3 / l m3 of fresh mortar, depending on the mortar (masonry or plaster) destination and its brand.
