Since the rediscovery of Roman concrete and the invention of reinforced concrete in the nineteenth century, concrete has been the subject of continual technological advancement, allowing ingredients to attain a diverse range of properties. This hybrid nature, which is further defined by a duality of states created by a mound, has been at the center of recent debates regarding the material's inherent elasticity in architecture. Consider the concept of smart concrete as a process rather than just a substance. Concrete has avoided having a set essential traditional and recognized aesthetics due to its extensive and varied history of technological improvements through research and practice. This material's multifaceted background has provided fertile ground for the search for new materiality. With the spread of emerging digital design and manufacturing technologies (CAD/CAM), this has become increasingly relevant in recent decades. They've sparked an increasing interest in rethinking concrete, while also assisting architects and builders in bridging the gap between design and construction. The purpose of this innovation is to study and present the emerging potential for concrete architecture that have been aided by the use of digital fabrication technologies in this context.

Summary of Invention
The first reinforced concrete prototypes, the concrete boat and conical vases, demonstrated the material's ability to create complicated shapes at an early age. Walter Gropius created a series of geometrically intriguing photographs of American silos and industrial buildings in concrete decades later, illustrating an early link between concrete and mobile forms in architecture. Reinforced concrete entered architecture as a result of the development of revolutionary construction technologies that offered up new spatial possibilities. However, it was its malleable characteristics, which allowed it to conform to any shape, that made it a perfect material for fascinating formal investigations, which modernist architects selected as the medium for a new architecture. During the first decades of the twentieth century, architects and engineers attempted to regulate the process of concrete materialisation by pushing the material's material, formal, and visual boundaries. The evaluation of concrete forms was particularly important in thin casing constructions among the many types of buildings. This form of structure, pioneered in the early 1930s by designer and engineer, demonstrated the plasticity of concrete in acquiring self behind and continuous curved surfaces of condensed thickness. Analysis methodology.
The inquiry began with a review of existing literature on relevant built works in which digital manufacturing played a significant role in the materialisation of

concrete elements. After that, a series of essential examples was chosen to highlight the range of comparable and disparate techniques that could support the classification suggestion for digital fabrication strategies. To organise the works considered for this research, a structure based on three sequential categories was defined:
1. Involvement mode
2. Digital Fabrication Technology
3. Theme Facing
The (1) Involvement Mode issue includes two options: direct and indirect, based on the current landscape of digital fabrication technologies and the dual state of the material (i.e. liquid and solid). This division distinguishes circumstances in which digital fabrication technology has a direct impact on the concrete building mechanism from those in which it is applied to other parts and subsequently has an indirect impact on the manufacture of concrete elements. A careful differentiation is made in the latter instance by examining the possibilities of intervening in the formwork or the reinforcement. Furthermore, given the bulk of the studied works focus on the fabrication of formwork, this topic had to be separated into different techniques based on its materiality: stiff, flexible, or dynamic.

As suggested, the (2) Digital Fabrication topic was separated into three categories: subtractive, additive, and formative. These topics were then separated into distinct fabrication technologies in order to show the differences between fabrication techniques within the same family. Brief description of the system
Examining Recent Research Developments, the use of digital fabrication technologies in the creation of concrete elements is becoming increasingly popular in academics. On the one hand, research groups have attempted to address some of the issues that have been identified in practice. On the other hand, they have attempted to suggest fresh paths that may eventually lead to new breakthroughs in practice. The summarizes the current research trends, which are then described and examined. Rigid Formwork / Subtraction / Indirect Intervention. The creation of formwork is still a major study topic, as evidenced by the majority of the examples considered. However, there is an interest in researching various ways for its manufacture with the use of digital fabrication. To be able to go beyond the restrictions of typical EPS milled formwork. Direct intervention / Subtractive fabrication.
All of the previous digital fabrication applications took place at different times prior to or during the concrete casting process. However, only a few have been discovered that directly convert the created concrete part into different shapes or

textures. For example, the erected at the Architecture Association in 2008 used approximately 850 glass fibre reinforced concrete panels that were cut with CNC technology, contemplating the usage of a concrete composite. In the fabrication of self-supporting assemblies, there have also been some trials with cutting precast concrete blocks with a diamond wire attached to a robotic arm. Both scenarios suggest that a CNC post-dispensation procedure could be used to materialize geometrically complicated assemblies directly over concrete materials.
