A bislauramide concrete foaming agent was prepared in good yield by a simple synthetic route using readily available hexamethylenediamine, 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, and shows evident synergistic effects with commercial concrete foaming agents.
