Disclosed are methods for incorporating core materials such as phase change materials or admixtures into building materials like concrete. The methods use cenospheres, which are then etched and loaded with the core material. The composition can also be coated with a thin film. Compositions containing cenospheres loaded with the various core materials are disclosed, as are building materials containing such compositions.

A composition includes: an ethoxylated fatty alcohol having from 8 to 22 carbon atoms and having an ethoxylation level of from 1 to 10 moles of ethylene oxide per mole of fatty alcohol, —an alkanolamine or a morpholine, or its derivatives or mix of them, and a fatty acid. A hydraulic binder includes the composition. A process prevents the formation of a surface film at the surface of hydraulic binders, wherein the composition is added to the dry hydraulic binder. A process for preparing the composition, includes: melting the ethoxylated fatty alcohol and heating it at a temperature above its melting point, adding water to the melted ethoxylated fatty alcohol and mixing, adding fatty acid to the mixture and mixing, adding alkanolamine or morpholine, or its derivative or mix of them to the mixture obtained and mixing, and adding water.
