3D Printed Mortar with High Alumina-Cement as Alternative Solution for Standard Materials Used for 3D Printing (2023-08)¶

3D printing of concrete is an innovative technology that is revolutionizing the construction industry. This advanced process allows the precise and automated production of durable concrete structures using cement-based binders for printing. 3D printing of concrete offers many advantages. First, the process makes it possible to create custom shapes and patterns that are difficult to achieve with traditional construction methods. In addition, the precise control of 3D printing can minimize the use of materials, which translates into cost savings and reduced environmental impact. Aluminum cement as a component of the binder causes a significant acceleration of the setting time, which can be useful in 3D printing technology. The research presented in the article analyzes the possibility of using aluminum cement to modify a concrete mixture for printing. The research shows that with the right composition of superplasticizer and binder, it is possible to achieve the required setting times.
