Abstract

3D concrete printing is an innovative technology for construction components as infrastructure, architecture, urban furniture, industrial molds, artificial and sculpturing. The mix in the 3D printer is similar yet varies in composition from the traditional ones. The process of the 3D concrete printing occurs when concrete is extruded through nozzles made of different sizes to form structure made of layer above layer hydration and adhesives are added to promote hydration and help the object maintain its shape, chopped binders are used to help reinforce the material and a liquid element is sprayed through the inkjet head to help bind the material, contributed with many advantages in the field of construction-related to print quality with no cracks and holes, shape stability as self-sustaining with no collapsing layers, high degree of compaction achievable without vibration, interlayered adhesion related to strength between layers. In addition to that, 3d printing construction process excludes certain types of materials, logistics and labor for them, such as formwork, which can significantly reduce the cost of construction, improving the quality and reliability of building a structure by eliminating the human factor – personnel incompetence and construction errors. Moreover, this presentation aims to present the concept and possibility of working on an aggregation between the cement for 3D printing and a crumb rubber tire. Taking into consideration the advantages of crumb rubber with traditional cement on a specific percentage of aggregation, as toughness resistance, insulations, water absorption, excellent machinal performance. So, the expectational work on the aggregation between cement for 3D printing and crumb rubber tire is to mix up the advantages of the two projects listed above in a new form material 3D Rubber/Crete printing.
