Preparation of novel foaming agent and its application in foam concrete

A novel foaming agent was prepared using animal hoof and horn as raw materials via calcium hydroxide as a catalyzer and the performanc of the product was measured. The results show that the expansion rate of foaming agent can be more than 20 times, and the stability of foaming is very excellent. The foaming agent was used for preparing foam concrete and the performanc of the foam concrete was also tested. The results show that the thermal conductivity can be kept between 0.055 and 0.234 W/(m.k), and the foam concrete possesses light masses, little density and well thermal insulation.
