Zoomlion mortar mixer Duo-mix for 3D-printed concrete construction
Zoomlion's wholly owned subsidiary, m-tec, has released its latest mortar mixer Duo-mix in Shanghai, China. The new solution, which can help to build a 60-cubic-metre two-storey house in two weeks with additive manufacturing techniques is now available in over 100 countries across Asia, Europe and North America.
The adaptable Duo-mix is designed especially for mortar used in 3D construction printing. It can process all standard dry mortar products ranging from bagged material or silo material to bucket coat materials up to a grain size of 4mm.
Duo-mix can be connected with back-end robots for 3D printing, and produce high-performance concrete with high compressive strength. It can also accurately adjust the construction speed according to the needs of the project, ensuring the strength of each layer of mortar, while maintaining the best adhesive ability even under humid conditions.
The Duo-mix is most suited to construction projects that are low budget and are on a tight time frame, such as exhibition sites, entertainment parks or conferences venues. The equipment also allows for external control via a mobile app for integrated higher-level of automation.
It can also improve construction quality, the environment of the construction site and solve labour shortage issues by using an automatic conveying and spraying technology for projects up to 60m wide and 30m in height.
