Book Description
3D Printing Technology is one of the most progressive technologies which is rapidly growing in the world of construction. This technology benefits by fast-tracking the speed of construction and reducing the labor cost, which allows more benefit economically and even providing structures with aesthetical looks, better strength and, durability aimed to be as good as casted concrete structures. To optimize the mix design and produce a workable concrete structure, Fused Deposition Modeling has been used for the printing process. The study is done to produce optimized proportions of concrete mix designs that are suitable for 3D printing of concrete. The addition of silica fume, nano- clay, and fly ash as non- cementitious material and superplasticizers, retarders, accelerators, and viscosity admixtures as chemical dosages are reported to control the flow of the concrete, bonding between the ingredients in the matrix and slowing down the hydration process, respectively which provides the structure with better stability. The 3D printing parameters like time, printability window, pressure variation, and other mechanical properties are studied in this research. FE- analysis can analyze the buildability of a specific shape or structure before printing. So that it can save the cost of materials and help with reducing the formation of 3D printed structure. Keywords: Supplementary Cementitious materials, Chemical Dosage, 3D printing parameters, and FE analysis.
