International Conference on Durability of Concrete Structures
Recently, additive manufacturing techniques such as 3D printing are becoming increasingly popular and widely used in a variety of applications. Inkjet 3D printing (i.e. powder-based printing) is one of the most reliable frequently-implemented techniques in 3D printers. This paper discusses a novel methodology to replace the currently used typical powders in 3D printing to make it possible to use the printed specimens in construction applications. The printed cubic (20Í20Í20mm) and prism (60Í5Í5mm) specimens with different saturation levels are printed to investigate the relative strength of the 3D printed specimens. Curing in different …

Environmental conditions have a significant effect on the mechanical properties of various materials. Environmental parameters such as temperature and humidity have a major impact on mechanical properties of materials such as compressive strength, tensile strength, bending strength and impact strength. The purpose of this research is to study how temperature and humidity affect the impact strength of 3D printed PLA plastic. Impact strength is the ability of a material to absorb energy subjected to an impact load by a pendulum. In this research, 3D printing was employed to produce PLA specimens which were later used for different experimental testings. For …

"3D printing is the process of creating three-dimensional objects using an automated additive manufacturing process. The 3D printing process has been used with materials such as metals and polymers, but application with cement based materials for the construction industry has yet to be developed. In this research, two main problems were investigated for printing cement based composite materials: extrudability and tensile reinforcement. Fiber-reinforced concrete (FRC) was studied as an internal reinforcing system to increase tensile/flexural strength. First, FRC was studied to investigate mechanical properties and use of fibers from waste tires as an environmentally friendly option. A reference mixture with …
