摘要
A cement mortar and concrete having a reduced water absorption and with a density of 2000-2500 kg/m.sup.3, at which it calculated on the amount of cement contains 0.2-10% by weight of a polymer in dispersion form consisting of polymeric particles containing hydropholic monomers from one or more of the groups acrylic monomers, methacrylic monomers and styrene and 1-15% calculated on the total amount of monomers of a methacrylate having an aliphatic chain of 12 or more carbons, preferably stearyl methacrylate.
