Alkylsilicone resins containing at least 20 mol percent of siloxy units bearing a >Calkyl group and having from 5-20 weight percent of alkoxy groups may be prepared directly by hydrolysis of chlorosilanes, and are highly effective as bulk hydrophobing agents in the preparation of fibrocement.

The invention relates to a method for operating a system at an operating temperature of between 300&#xb0; C. and 500&#xb0; C., using a heat transfer fluid comprising branched siloxanes of general formula (I) (RSiO), (SiO) in which w represents integral values of between 4 and 20, z represents integral values of between 1 and 15, and R represents a methyl group, the sum of the fractions of all siloxanes of general formula (1) being at least 95 mass %, in relation to the whole heat transfer fluid.
