Dodecanamide Concrete Foaming Agent: Preparation and Application

Abstract:

A lauramide concrete foaming agent was prepared by a simple synthetic route using readily available N-(2-hydroxyethyl)ethylenediamine, dodecanoic acid, and chloroacetic acid. The reaction conditions were optimized by changing reaction temperature, reaction time, and/or molar ratios of reactants. Significantly, the concrete foaming agent has very low surface tension and good foaming properties, which could be directly used without purification and has widely applicable potentials in low-density foam concrete.
