CARACTERÍSTICAS REOLÓGICAS PARA ARGAMASSA 3D: UMA REVISÃO

Abstract

Additive manufacturing has become one of the most popular technologies, as it is an innovation that prints three-dimensional objects from beginning to end. This technology can also be applied in civil construction through the concrete/mortar extrusion method. Studies on the application of the 3D printer in construction have grown a lot in recent years due to the advantages that the system provides, such as: cost reduction, versatility, minimal waste and lack of forms. However, the application of this innovation presents some challenges, among them is the production of a mortar that meets particular parameters for digital construction. Due to the peculiarity of the printed mortar, this work proposes to present a bibliographic review of the subject in the last 5 years, with the objective of identifying primordial parameters to guarantee the printing of the mass, in addition to verifying the specific criteria in the composition, granulometry, in the performance rheological and workability for a mortar to be considered acceptable for 3D printing and its development methodology. It is concluded that characteristics in the preparation such as different granulometric shapes, different compositions, as well as a high content of chemical additives can interfere with the performance of the mass, in this way it is essential to carry out rheological tests before printing, to obtain a mixture of quality, structural stability and ensuring good digital construction.
