The invention concerns aqueous emulsions of (A) organopolysiloxane free from basic nitrogen and (B) alkyltrialkoxysilane which contain (C) an emulsifier and (D) water. Organopolysiloxane (A) has formula RaSi(OR1)bO4-a-b/2, wherein R has ident- ical or different, monovalent, optionally substituted C1-C18 hydrocarbon residues bonded by SiC, R1 has identical or differ- ent, monovalent, optionally substituted C1-C6 hydrocarbon residues, a is equal to 0,1,2 or 3, on average 0.75 to 1.5, and b is equal to 1, 2 or 3, on average 0.2 to 2.0, and has a molecular weight of at least 600 g/mol. Also disclosed are a method for preparing said emulsions and their use for water-repellent impregnation of cement-bonded fibrous building components.
