Glutamine-rich peptides as air-entraining agents in building materials

摘要

Use of glutamine-rich peptide or peptide mixture as an air entraining agent in the hydraulically curable building material, is claimed, where the peptide contains at least 16 wt.% of glutamine. An independent claim is included for a composition comprising at least one peptide comprising at least 16 wt.% of glutamine based on the total mass of the peptide.
