Abstract
Oggetto dell'invenzione è un procedimento per migliorare le proprietà di rimbalzo di calcestruzzo applicato a spruzzo il quale consiste nell'includere in esso una micro-silice che sia stata preliminarmente trattata con da 2 a 25% in peso di un liquido scelto fra acqua, una alcanolammina, un poliolo ed una soluzione acquosa di almeno un additivo per calcestruzzo, una alcanolammina, un poliolo ed un composto cellulosico solubile in acqua. Il procedimento è particolarmente efficace quando impiegato insieme con un procedimento di spruzzatura a secco.
