Abstract:
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.
