Abstract

Un miscuglio additivo da impiegare in composizioni cementizie che debbono essere applicate in strati consecutivi consiste essenzialmente di un ossido polialchilenico solubile in acqua e di un materiale superassorbente. Facoltativamente (e preferibilmente) è presente anche un agente plasticizzante o superplasticizzante, preferibilmente un copolimero di stirene ed anidride maleica modificato con ossido polialchilenico.
