Animal Protein-Based Foaming Agents in Lightweight Concrete: Chemistry, Performance, and Innovation expandable foam for concrete
1. Origin, Composition, and Molecular Architecture 1.1 Natural Resource and Biochemical Account (Animal Protein Frothing Agent) Pet protein-based lathering agents are obtained mostly from hydrolyzed keratin or collagen sourced from slaughterhouse byproducts such as unguis, horns, bones, and hides. Via controlled alkaline or enzymatic hydrolysis, these architectural proteins are damaged down into amphiphilic polypeptides rich
