| New type of building material using natural adhesives |
Xinhua News Agency quoted expert Wang Shutao of the Institute of Physical and Chemical Engineering (TIPC) of the Chinese Academy of Sciences as saying that traditional cement-based construction materials consume a lot of energy during production and emit a lot of CO2 .
TIPC researchers observed a special species of marine worm, called the sandcastle worm, which has a unique way of building its nests. It secretes a solution that binds sand grains or pieces of shell together to form sandcastles. From this observation, scientists have developed a new building material using a naturally occurring adhesive.
According to research, this new construction material is very flexible, able to bond many different types of sand such as desert sand, sea sand, concrete slag, coal slag and mineral residue.
This material has good mechanical performance, unique recyclability, resistance to all weather conditions and elasticity.
