Chinese scientists develop novel "marshmallow" concrete to gently stop aircraft during emergency landings
Chinese researchers have created a revolutionary runway safety system using ultra-lightweight foam concrete, nicknamed
"For example, water pools tend to freeze in winter and attract animals, while the soil surfaces are highly sensitive to environmental humidity and temperature, with unstable mechanical properties," said Fang. To develop an extraordinary ability to absorb energy through fracturing, the mechanical collapse performance of ultra-light foam concrete must be precisely controlled. International technical proposals utilize calcium sulfoaluminate cement as a raw material, which offers advantages such as rapid hardening and reduces forming difficulties.
