Beschreibung
Zusammenfassung:A mortar contains cement, one or more than one mineral additive, superplasticizer, aggregates, a hydroxyethyl methyl cellulose and water, wherein the hydroxyethyl methyl cellulose is characterized by the sum of its hydroxyethyl molecular substitution and methyl degree of substitution is 1.90 or higher and 2.30 or lower and its viscosity as a 2 weight-percent aqueous solution that is below 30,000 milliPascals*seconds. L'invention concerne un mortier qui contient du ciment, un ou plusieurs additifs minéraux, un superplastifiant, des agrégats, une hydroxyéthylméthylcellulose et de l'eau, l'hydroxyéthylméthylcellulose se caractérisant par la somme de sa substitution moléculaire d'hydroxyéthyle et du degré de substitution de méthyle qui est supérieure ou égale à 1,90 et inférieure ou égale à 2,30, et une viscosité en solution aqueuse à 2 pourcent en poids qui est inférieure à 30 000 milliPascals*secondes.
