With the increasing aging population and the pressure of global climate change, it is inevitable for the construction industry to develop towards automation and energy conservation.
3D concrete printing technology can automatically and accurately lay materials to the required locations, saving labor and materials, and is a new way for the industry to upgrade.
But it has a key issue – the bonding strength between the printing layers is not sufficient, which can result in inconsistent strength and durability of the concrete, and also shorten the service life of the building, which has always constrained the practical application of this technology.
